Removed sparse warnings from tg3 driver. The new logic seems fine (I
don't immediately see where we are running over values for any of the
variables that need to be saved).
This patch compiles fine and I'm currently using a tg3 with the patched
driver to post this patch as a basic proof of concept.

This dongle does not follow the usb-irda specification, so it needs its own
special driver. First, it uses control URBs for data transfer, instead of
bulk or interrupt transfers; the only interrupt endpoint exposed seems to
be a dummy to prevent the interface from being rejected. Second, it uses
obfuscation and padding at the USB traffic level, for no apparent reason
other than to make reverse engineering harder (full details on obfuscation
in comments at beginning of source). Although it is advertised as a "4 Mbps
FIR dongle", it apparently loses packets at speeds greater than 57600 bps.
On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4959 .
The Windows driver that is used normally to control this dongle has a
filename of KS-959.SYS .

This dongle does not follow the usb-irda specification, so it needs its own
special driver. Just like the Kingsun/Donshine dongle, it exposes two
interrupt endpoints. Reception is performed through direct reads from the
input endpoint. Transmission requires splitting the IrDA frames into 8-byte
segments, in which the first byte encodes how many of the remaining 7 bytes
are used as data. Speed change is made with a control URB just like the one
in cypress_m8, and it seems to support up to 115200 bps.
On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4100

Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>.
This patch introduces support for dynamic reconfiguration (adding, removing
and/or modifying parameters of netconsole targets at runtime) using a
userspace interface exported via configfs. Documentation is also updated
accordingly.
Issues and brief design overview:
(1) Kernel-initiated creation / destruction of kernel objects is not
possible with configfs -- the lifetimes of the "config items" is managed
exclusively from userspace. But netconsole must support boot/module
params too, and these are parsed in kernel and hence netpolls must be
setup from the kernel. Joel Becker suggested to separately manage the
lifetimes of the two kinds of netconsole_target objects -- those created
via configfs mkdir(2) from userspace and those specified from the
boot/module option string. This adds complexity and some redundancy here
and also means that boot/module param-created targets are not exposed
through the configfs namespace (and hence cannot be updated / destroyed
dynamically). However, this saves us from locking / refcounting
complexities that would need to be introduced in configfs to support
kernel-initiated item creation / destroy there.
(2) In configfs, item creation takes place in the call chain of the
mkdir(2) syscall in the driver subsystem. If we used an ioctl(2) to
create / destroy objects from userspace, the special userspace program is
able to fill out the structure to be passed into the ioctl and hence
specify attributes such as local interface that are required at the time
we set up the netpoll. For configfs, this information is not available at
the time of mkdir(2). So, we keep all newly-created targets (via
configfs) disabled by default. The user is expected to set various
attributes appropriately (including the local network interface if
required) and then write(2) "1" to the "enabled" attribute. Thus,
netpoll_setup() is then called on the set parameters in the context of
_this_ write(2) on the "enabled" attribute itself. This design enables
the user to reconfigure existing netconsole targets at runtime to be
attached to newly-come-up interfaces that may not have existed when
netconsole was loaded or when the targets were actually created. All this
effectively enables us to get rid of custom ioctls.
(3) Ultra-paranoid configfs attribute show() and store() operations, with
sanity and input range checking, using only safe string primitives, and
compliant with the recommendations in Documentation/filesystems/sysfs.txt.
(4) A new function netpoll_print_options() is created in the netpoll API,
that just prints out the configured parameters for a netpoll structure.
netpoll_parse_options() is modified to use that and it is also exported to
be used from netconsole.

This patch introduces support for multiple targets, independent of
CONFIG_NETCONSOLE_DYNAMIC -- this is useful even in the default case and
(including the infrastructure introduced in previous patches) doesn't really
add too many bytes to module text. All the complexity (and size) comes with
the dynamic reconfigurability / userspace interface patch, and so it's
plausible users may want to keep this enabled but that disabled (say to avoid
a dependency on CONFIG_CONFIGFS_FS too).
Also update documentation to mention the use of ";" separator to specify
multiple logging targets in the boot/module option string.
Brief overview:
We maintain a target_list (and corresponding lock). Get rid of the static
"default_target" and introduce allocation and release functions for our
netconsole_target objects (but keeping sure to preserve previous behaviour
such as default values). During init_netconsole(), ";" is used as the
separator to identify multiple target specifications in the boot/module option
string. The target specifications are parsed and netpolls setup. During
exit, the target_list is torn down and all items released.

Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>.
To update fields of underlying netpoll structure at runtime on corresponding
NETDEV_CHANGEADDR or NETDEV_CHANGENAME notifications.
ioctl(SIOCSIFHWADDR or SIOCSIFNAME) could be used to change the hardware/MAC
address or name of the local interface that our netpoll is attached to.
Whenever this happens, netdev notifier chain is called out with the
NETDEV_CHANGEADDR or NETDEV_CHANGENAME event message. We respond to that and
update the local_mac or dev_name field of the struct netpoll. This makes
sense anyway, but is especially required for dynamic netconsole because the
netpoll structure's internal members become user visible files when either
sysfs or configfs are used. So this helps us to keep up with the MAC
address/name changes and keep values in struct netpoll uptodate.
[ Note that ioctl(SIOCSIFADDR) to change IP address of interface at
runtime is not handled (to update local_ip of netpoll) on purpose --
some setups may set the local_ip to a private address, not necessary
the actual IP address of the sender host, as presently allowed. ]

Introduce a wrapper structure over netpoll to represent logging targets
configured in netconsole. This will get extended with other members in
further patches.
This is done independent of the (to-be-introduced) NETCONSOLE_DYNAMIC config
option so that we're able to drastically cut down on the #ifdef complexity of
final netconsole.c. Also, struct netconsole_target would be required for
multiple targets support also, and not just dynamic reconfigurability.

Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>.
Presently, boot/module parameters are set up quite differently for the case of
built-in netconsole (__setup() -> obsolete_checksetup() ->
netpoll_parse_options() -> strlen(config) == 0 in init_netconsole()) vs
modular netconsole (module_param_string() -> string copied to the config
variable -> strlen(config) != 0 init_netconsole() -> netpoll_parse_options()).
This patch makes both of them similar by doing exactly the equivalent of a
module_param_string() in option_setup() also -- just copying the param string
passed from the kernel command line into "config" variable. So,
strlen(config) != 0 in both cases, and netpoll_parse_options() is always
called from init_netconsole(), thus making the setup logic for both cases
similar.
Now, option_setup() is only ever called / used for the built-in case, so we
put it inside a #ifndef MODULE, otherwise gcc will complain about
option_setup() being "defined but not used". Also, the "configured" variable
is redundant with this patch and hence removed.

The (!np.dev) check in write_msg() is bogus (always false), because: np.dev is
set by netpoll_setup(), which is called by init_netconsole() before
register_console(), so write_msg() cannot be triggered unless netpoll_setup()
successfully set np.dev. Also np.dev cannot go away from under us, because
netpoll_setup() grabs us reference on it. So let's remove the bogus check.

Veth stands for Virtual ETHernet. It is a simple tunnel driver
that works at the link layer and looks like a pair of ethernet
devices interconnected with each other.
Mainly it allows to communicate between network namespaces but
it can be used as is as well.
The newlink callback is organized that way to make it easy to
create the peer device in the separate namespace when we have
them in kernel.
This implementation uses another interface - the RTM_NRELINK
message introduced by Patric.

Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.
In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.
The signature of the ->poll() call back goes from:
int foo_poll(struct net_device *dev, int *budget)
to
int foo_poll(struct napi_struct *napi, int budget)
The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract). The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.
The napi_struct is to be embedded in the device driver private data
structures.
Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler. Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.
With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

Similarly to CTS protection, whether short preambles are used for 802.11b
transmissions should be a per-subif setting, not device global.
For STAs, this patch makes short preamble handling automatic based on the ERP
IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been
restricted to AP-only subifs.
ieee80211_txrx_data.short_preamble (an unused field) was removed.
Unfortunately, some API changes were required for the following functions:
- ieee80211_generic_frame_duration
- ieee80211_rts_duration
- ieee80211_ctstoself_duration
- ieee80211_rts_get
- ieee80211_ctstoself_get

The Yukon FE+ chip appears to have a hardware glitch that causes bogus
receive status values to be posted. The data in the packet is good, but
the status value is random garbage. As a temporary workaround until the
problem is better understood, implement the workaround the vendor driver
used of ignoring the status value on this chip.
Since this means trusting dodgy hardware values; add additional checking
of the receive packet length.

The 8168 ignores the requests to fetch the Tx descriptors when
the relevant TxPoll bit is already set. It easily kills the
performances of the 8168. David Gundersen has noticed that it
is enough to wait for the completion of the DMA transfer (NPQ
bit is cleared) before writing the TxPoll register again.
The extra IO traffic added by the proposed workaround could be

The phys of the 8110SC (RTL_GIGA_MAC_VER_{05/06}) act abnormally in
gigabit mode if they are applied the parameters in rtl8169_hw_phy_config
which actually aim the 8110S/SB.
It is ok to return early from rtl8169_hw_phy_config as it does not
apply to the 8101 and 8168 families.

This reverts commit fadacb1b80e35e0b36a90d43e21ef91eec4b889b.
The change being reverted made the driver consistent with
include/linux/netdevice.h, but then inconsistent with the other PCMCIA
ethernet drivers.

Be more selective about when to enable the ram buffer watchdog code.
It is unnecessary on XL A3 or later revs, and with Yukon FE
the buffer is so small (4K) that the watchdog detects false positives.

This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify
cloned skb data. It also gets rid of skb2 we only need to preserve the
original skb for congestion notification, which is only applicable for
ppp_async and ppp_sync.
The other semantic change made here is the removal of socket accounting
for data tranmitted out of pppol2tp_xmit. The original code leaked any
existing socket skb accounting. We could fix this by dropping the
original skb owner. However, this is undesirable as the packet has not
physically left the host yet.
In fact, all other tunnels in the kernel do not account skb's passing
through to their own socket. In partciular, ESP over UDP does not do
so and it is the closest tunnel type to PPPoL2TP. So this patch simply
removes the socket accounting in pppol2tp_xmit. The accounting still
applies to control packets of course.
I've also added a reminder that the outgoing checksum here doesn't work.
I suppose existing deployments don't actually enable checksums.

The function pppol2tp_recv_core doesn't handle non-linear packets properly.
It also fails to check the remote offset field.
This patch fixes these problems. It also removes an unnecessary check on
the UDP header which has already been performed by the UDP layer.

With the addition of UDP-Lite we need to refine the socket check so
that only genuine UDP sockets are allowed through.

When I got rid of the second packet in __pppoe_xmit I created
a double-free on the skb because of the goto abort on failure.
This patch removes that.

A driver writer from another operating system hinted that
the versions of Yukon 2 chip with rambuffer (EC and XL) have
a hardware bug that if the FIFO ever gets completely full it
will hang. Sounds like a classic ring full vs ring empty wrap around
bug.
As a workaround, use the existing watchdog timer to check for
ring full lockup.

Add support for newest Marvell chips.
The Yukon FE plus chip is found in some not yet released laptops.
Tested on hardware evaluation boards.
This version of the patch is for 2.6.23. It supersedes
the two previous patches that are sitting in netdev-2.6 (upstream branch).
