This supercedes the older patch ("cw1200: Don't perform SPI transfers in
interrupt context") that badly attempted to fix this problem.
This is a far simpler solution, which has the added benefit of
actually working.

This reverts commit aec8e88c947b7017e2b4bbcb68a4bfc4a1f8ad35.
This solution turned out to cause interrupt delivery problems, and
rather than trying to fix this approach, it has been scrapped in favor
of an alternative (and far simpler) implementation.

For pcie8897, the hs_cfg cancel command (0xe5) times out when host
comes out of suspend. This is caused by an incompleted host sleep
handshake between driver and firmware.
Like SDIO interface, PCIe also needs to go through firmware power
save events to complete the handshake for host sleep configuration.
Only USB interface doesn't require power save events for hs_cfg.

The private array at the end of the rtl_priv struct is not aligned.
On ARM architecture, this causes an alignment trap and is fixed by aligning
that array with __align(sizeof(void *)). That should properly align that
space according to the requirements of all architectures.

The commit "ath9k: Optimize LNA check" tried
to use the "rs_firstaggr" flag to optimize the LNA
combining algorithm when processing subframes in
an A-MPDU. This doesn't appear to work well in practice,
so revert it and use the old method of relying on
"rs_moreaggr".

When the dlc is closed, rfcomm_dev_state_change() tries to release the
port in the case it cannot get a reference to the tty. However this is
racy and not even needed.
Infact as Peter Hurley points out:
1. Only consider dlcs that are 'stolen' from a connected socket, ie.
reused. Allocated dlcs cannot have been closed prior to port
activate and so for these dlcs a tty reference will always be avail
in rfcomm_dev_state_change() -- except for the conditions covered by
#2b below.
2. If a tty was at some point previously created for this rfcomm, then
either
(a) the tty reference is still avail, so rfcomm_dev_state_change()
will perform a hangup. So nothing to do, or,
(b) the tty reference is no longer avail, and the tty_port will be
destroyed by the last tty_port_put() in rfcomm_tty_cleanup.
Again, no action required.
3. Prior to obtaining the dlc lock in rfcomm_dev_add(),
rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to
do here.
4. After releasing the dlc lock in rfcomm_dev_add(),
rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a
tty reference could not be obtained. Again, the best thing to do here
is nothing. Any future attempted open() will block on
rfcomm_dev_carrier_raised(). The unconnected device will exist until
released by ioctl(RFCOMMRELEASEDEV).
The patch removes the aforementioned code and uses the
tty_port_tty_hangup() helper to hangup the tty.

We need to let the setup stage complete cleanly even when the HCI device
is rfkilled. Otherwise the HCI device will stay in an undefined state
and never get notified to user space through mgmt (even when it gets
unblocked through rfkill).
This patch makes sure that hci_dev_open() can be called in the HCI_SETUP
stage, that blocking the device doesn't abort the setup stage, and that
the device gets proper powered down as soon as the setup stage completes
in case it was blocked meanwhile.
The bug that this patch fixed can be very easily reproduced using e.g.
the rfkill command line too. By running "rfkill block all" before
inserting a Bluetooth dongle the resulting HCI device goes into a state
where it is never announced over mgmt, not even when "rfkill unblock all"
is run.

This makes it more convenient to check for rfkill (no need to check for
dev->rfkill before calling rfkill_blocked()) and also avoids potential
races if the RFKILL state needs to be checked from within the rfkill
callback.

For certain devices (ex: HID mouse), support for authentication,
pairing and bonding is optional. For such devices, the ACL alive
for too long after the L2CAP disconnection.
To avoid the ACL alive for too long after L2CAP disconnection, reset the
ACL disconnect timeout back to HCI_DISCONN_TIMEOUT during L2CAP connect.
While merging the commit id:a9ea3ed9b71cc3271dd59e76f65748adcaa76422
this issue might have introduced.

This patch fixes the connection encryption key size information when
the host is playing the peripheral role. We should set conn->enc_key_
size in hci_le_ltk_request_evt, otherwise it is left uninitialized.

While playing the peripheral role, the host gets a LE Long Term Key
Request Event from the controller when a connection is established
with a bonded device. The host then informs the LTK which should be
used for the connection. Once the link is encrypted, the host gets
an Encryption Change Event.
Therefore we should set conn->pending_sec_level instead of conn->
sec_level in hci_le_ltk_request_evt. This way, conn->sec_level is
properly updated in hci_encrypt_change_evt.
Moreover, since we have a LTK associated to the device, we have at
least BT_SECURITY_MEDIUM security level.

As mentioned by Joe Perches, clean up return values in some functions
making sure to have consistent return types, not mixing types.
A couple of Joe's comments suggested returning void, but since
the functions in question are ndo defined, the return values are fixed.
So make a comment in the header that notes this is a function called by
net_device_ops.
v2: fix post increment bug in return

When calling admin queue functions the driver should use aq_ret
variable to help make clear that the return value is not a regular
return variable.
This allows for clean up of the return types that were previously
converted to int.

In the following scenario the socket is corked:
If the first UDP packet is larger then the mtu we try to append it to the
write queue via ip6_ufo_append_data. A following packet, which is smaller
than the mtu would be appended to the already queued up gso-skb via
plain ip6_append_data. This causes random memory corruptions.
In ip6_ufo_append_data we also have to be careful to not queue up the
same skb multiple times. So setup the gso frame only when no first skb
is available.
This also fixes a shortcoming where we add the current packet's length to
cork->length but return early because of a packet > mtu with dontfrag set
(instead of sutracting it again).

In my patch c194992cbe71c20bb3623a566af8d11b0bfaa721 ("skge: fix
broken driver") I didn't fix the skge bug correctly. The value of the
new mapping (not old) was passed to pci_unmap_single.
If we enable CONFIG_DMA_API_DEBUG, it results in this warning:
WARNING: CPU: 0 PID: 0 at lib/dma-debug.c:986 check_sync+0x4c4/0x580()
skge 0000:02:07.0: DMA-API: device driver tries to sync DMA memory it has
not allocated [device address=0x000000023a0096c0] [size=1536 bytes]
This patch makes the skge driver pass the correct value to
pci_unmap_single and fixes the warning. It copies the old descriptor to
on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.
This patch should be backported to 3.11-stable.

MRP doesn't implement the periodictimer in 802.1Q, so it never retries
if packets get lost. I ran into this problem when MRP sent a MVRP
JoinIn before the interface was fully up. The JoinIn was lost, MRP
didn't retry, and MVRP registration failed.

Commit b9871bcf "bnx2x: VF RSS support - PF side" has deprecated one of
the previous existing messages. If an old VF driver were to send this message
to the PF then the PF will not reply and leave the mailbox in an unsteady
state (and cause a timeout on the VF side).

During flows which mask block attentions (e.g., register dump) all parities
are masked. However, unlike other blocks the MCP's attention is not masked
inside the block but rather the indication to the driver. If another attention
(e.g., link change) will occour while there's an MCP parity, the driver will
ignore the fact that the parity is masked and erroneously report a parity.
This patch forces the driver to read the MCP masking while checking for
parities.

When system CPU is stressed it's possible that the driver will not be able
to pulse the FW every second, which will cause the log to be filled with
error messages.
Increasing the threshold to 5 seconds seems to be enough to eliminate the
issue.

On 848xx PHY (10G-baseT), half-duplex was always advertised regardless of the
actual configuration. Change the 848xx duplex settings to advertise half-duplex
only if configured.

when 1G-optic module was plugged in, internal loopback test failed because the
driver used to check the optic module (with no need), and for 1G optic module,
the link speed was forced down to 1G, while the XMAC (10G MAC) was enabled.
This patch avoid accessing optic module in case internal loopback was selected,
and update the link speed in case 1G optic module was detected during init
stage.

Relocate bnx2x_disable_kr2 function, and use it to disable KR2 in case it is not
configured in order to clear it's configuration, otherwise the link may come up
at 20G instead of the requested 10G-KR. In addition, restart AN after
disabling KR2 as part of the KR2 work-around.

Previously, in case of KR link down, the driver would reset the PHY and restart
auto negotiation only when old Warpcore microcode was used (below D108).
This patch comes to generalize this by keep trying to restart KR link,
regardless of Warpcore microcode, since it was found that it solves another link
issue which source is a link-partner. As part of this change, the signal
detect is no longer a condition to apply the work-around to cover this new case.
Like before, as long as the link is down, AN will be restarted every 2 seconds.
