qlogicpti driver registers its irq with a name containing slash.
This results in
[ 71.049735] WARNING: at fs/proc/generic.c:316 __xlate_proc_name+0xa8/0xb8()
[ 71.132815] name 'Qlogic/PTI'
because proc_mkdir with the name of the irq fails. Fix it by just
removing the slash from irq name. Discovered and tested on real hardware
(Sun Ultra 1).

Thanks Mikael.
Anonymity has some good attributes.
Blame avoidance is one of them.
I've broad shoulders. It's me, then Dwight Howard...
There might be another few of these where ->name or ->dev
was used before struct device or net_device was registered.
I'll go back and check.
tulip_core has:
if (tp->flags & HAS_MEDIA_TABLE) {
sprintf(dev->name, DRV_NAME "%d", board_idx); /* hack */
tulip_parse_eeprom(dev);
strcpy(dev->name, "eth%d"); /* un-hack */
}
So I don't feel _too_ bad.
tulip_parse_eeprom is done before register_netdev so the logging
there can not use netdev_<level> or dev_<level>(&dev->dev

If we are managing IPv6 addresses using DHCP, it would be nice
for user-space to be notified if an address configured through
DHCP fails DAD. Otherwise user-space would have to poll to see
whether DAD succeeds.
This patch uses the existing notification mechanism and simply
hooks it into the DAD failure code path.

This reverts commit 21b2d8bd2f0d4e0f21ade147fd193c8b9c1fd2b9.
As explained by Johannes:
When we
build a probe request frame in the buffer with the SSID, we could
arrive over the limit of 200 bytes. When we build it in the buffer
without the SSID (wildcard) we don't arrive over 200 bytes, but the
ucode still allows direct probe in addition because it has an internal
buffer that is larger when it inserts the SSID...

Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory
corruption problem. When initializing the clip groups the code was
mistakenly using the iwlagn rate count, not the 3945 rate count. This
resulted in more memory being written than was allocated.
"iwlwifi: move 3945 clip groups to 3945 data" moved the location where the
clip groups are stored and the impact is now severe in that the number of
configured TX queues is modified. Previously the
"temperature" field was overwritten, which did not seem to affect the
operation.
Fix this one instance where wrong rate count was used. I also noticed one
more location where the iwlagn rate count was used to index an iwl3945
array, fix this. I also modified one location that modified the iwlagn rate
count to obtain the iwl3945 rate count ... just use the iwl3945 rate count
directly.
This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2165 and

we read the IQ correction values (i_cal and q_cal) for G mode from a wrong
location (the same shifts as for A mode is applied which is incorrect). use
correct locations, matching the docs and HAL sources.
also we should write IQ correction only when we have that information in the
EEPROM, starting from version 4. also write it in the same way as we do in the
periodic recalibration (enable last), just to be sure.

I/Q calibration was completely broken, resulting in a high number of CRC errors
on received packets. before i could see around 10% to 20% CRC errors, with this
patch they are between 0% and 3%.
1.) the removal of the mask in commit "ath5k: Fix I/Q calibration
(f1cf2dbd0f798b71b1590e7aca6647f2caef1649)" resulted in no mask beeing used
when writing the I/Q values into the register. additional errors in the
calculation of the values (see 2.) resulted too high numbers, exceeding the
masks, so wrong values like 0xfffffffe were written. to be safe we should
always use the bitmask when writing parts of a register.
2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we
convert to a signed value later by substracting 128. this resulted in too low
numbers for Q many times, which were limited to -16 by the boundary check later
on.
3.) checked everything against the HAL sources and took over comments and minor
optimizations from there.
4.) we can't use ENABLE_BITS when we want to write a number (the number can
contain zeros). also always write the correction values first and set ENABLE
bit last, like the HAL does.

when using a fixed antenna we should use the antenna number in all tx
descriptors, otherwise the hardware will sometimes send the frame out on the
other antenna. it seems like the hardware does not always respect the default
antenna and diversity settings (esp. AR5K_STA_ID1_DEFAULT_ANTENNA).
also i would like to note that antenna diversity does not always work correctly
on 5414 (at least) when only one antenna is connected: for example all frames
might be received on antenna A but still the HW tries to send on antenna B some
times, causing packet loss.
this is both verified with the antenna statistics output of the previous patch
and a spectrum analyzer.

The ieee->networks consists of 128 struct libipw_network entries. If
we allocate this chunk of memory altogether, it ends up with an
order 4 page allocation. High order page allocation is likely to fail
on system high load. This patch splits the big chunk memory allocation
into small pieces, each is 344 bytes, allocates them with 128 times.

Commit 34e895075e21be3e21e71d6317440d1ee7969ad0 introduced sta_mtx
locking into sta_info_insert() (now sta_info_insert_rcu), but forgot
to unlock this mutex on one of the error paths. Fix this by adding
the missing mutex_unlock() call for the case where STA insert fails
due to an entry existing already. This may happen at least in AP mode
when a STA roams between two BSSes (vifs).

Some network devices, particularly USB ones, take several seconds to
fully init and appear in the device list.
If the user turned ipconfig on, they are using it for NFS root or some
other early booting purpose. So it makes no sense to just flat out
fail immediately if the device isn't found.
It also doesn't make sense to just jack up the initial wait to
something crazy like 10 seconds.
Instead, poll immediately, and then periodically once a second,
waiting for a usable device to appear. Fail after 12 seconds.

Deactivate inbound checksumming on HiperSocket is a valid but
dangerous optimization in case the frame is routed from an OSA
network to an HiperSockets network. To go for sure we change the
default to software checksumming.

Depending on their definition in z/VM, virtual devices for z/VM
VSWITCH or GuestLAN must be configured either in layer2 or in
layer3 mode. If qeth detects a layer mismatch, device activation
fails. Trying to recover from this error cannot help; thus
scheduling a recovery should be avoided.
In addition, since recovery is forbidden during online setting of
a qeth device, existence of its network device is guaranteed for all
dev_close() calls in qeth. The corresponding checks can be removed.

If HiperSockets Network Traffic Analyzer is switched off, but trace
disabling fails somehow, the qeth driver does not switch off its
promisc mode status. A following sniffer reactivation fails, since
qeth does not see a need to reenable tracing.
At the same time the code analyzing results of trace commands is
restructured.

Port commit 20deb48d16fdd07ce2fdc8d03ea317362217e085
from git://tipc.cslab.ericsson.net/pub/git/people/allan/tipc.git
Part of the large effort I'm trying to help with getting all the downstreamed
code from windriver forward ported to the upstream tree
Origional commit message
Restore check to filter out inadverdently received messages
This patch reimplements a check that allows TIPC to discard messages
that are not intended for it. This check was present in TIPC 1.5/1.6,
but was removed by accident during the development of TIPC 1.7; it has
now been updated to account for new features present in TIPC 1.7 and
reinserted into TIPC. The main benefit of this check is to filter
out messages arriving from orphaned link endpoints, which can arise
when a node exits the network and then re-enters it with a different
TIPC network address (i.e. <Z.C.N> value).

Remove htohl implementation from tipc
I was working on forward porting the downstream commits for TIPC and ran accross this one:
http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31e
I was going to just take it, when I looked closer and noted what it was doing.
This is basically a routine to byte swap fields of data in sent/received packets
for tipc, dependent upon the receivers guessed endianness of the peer when a
connection is established. Asside from just seeming silly to me, it appears to
violate the latest RFC draft for tipc:
http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt
Which, according to section 4.2 and 4.3.3, requires that all fields of all
commands be sent in network byte order. So instead of just taking this patch,
instead I'm removing the htohl function and replacing the calls with calls to
ntohl in the rx path and htonl in the send path.
As part of this fix, I'm also changing the subscr_cancel function, which
searches the list of subscribers, using a memcmp of the entire subscriber list,
for the entry to tear down. unfortunately it memcmps the entire tipc_subscr
structure which has several bits that are private to the local side, so nothing
will ever match. section 5.2 of the draft spec indicates the <type,upper,lower>
tuple should uniquely identify a subscriber, so convert subscr_cancel to just
match on those fields (properly endian swapped).
I've tested this using the tipc test suite, and its passed without issue.

We added an automatic route cache rebuilding in commit 1080d709fb9d8cd43
but had to correct few bugs. One of the assumption of original patch,
was that entries where kept sorted in a given way.
This assumption is known to be wrong (commit 1ddbcb005c395518 gave an
explanation of this and corrected a leak) and expensive to respect.
Paweł Staszewski reported to me one of his machine got its routing cache
disabled after few messages like :
[ 2677.850065] Route hash chain too long!
[ 2677.850080] Adjust your secret_interval!
[82839.662993] Route hash chain too long!
[82839.662996] Adjust your secret_interval!
[155843.731650] Route hash chain too long!
[155843.731664] Adjust your secret_interval!
[155843.811881] Route hash chain too long!
[155843.811891] Adjust your secret_interval!
[155843.858209] vlan0811: 5 rebuilds is over limit, route caching
disabled
[155843.858212] Route hash chain too long!
[155843.858213] Adjust your secret_interval!
This is because rt_intern_hash() might be fooled when computing a chain
length, because multiple entries with same keys can differ because of
TOS (or mark/oif) bits.
In the rare case the fast algorithm see a too long chain, and before
taking expensive path, we call a helper function in order to not count
duplicates of same routes, that only differ with tos/mark/oif bits. This
helper works with data already in cpu cache and is not be very
expensive, despite its O(N^2) implementation.
Paweł Staszewski sucessfully tested this patch on his loaded router.

For promiscuous mode, driver send request to device for deleting
multicast addresses and again it send request for adding them back
while exiting from this mode, this is bad for performance.
Just setting device in promiscuous mode is enough, no need to del/add
