143d40f3ab Revert "ipw2200: fix oops on missing firmware"
This reverts commit e6c5fc53d0.

Based on this regression report:

Date: Thu, 05 Nov 2009 15:59:16 +0100
From: Holger Schurig <holgerschurig@gmail.com>
To: linux-wireless@vger.kernel.org
Subject: BUG: oops when "rmmod ipw2200"

This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I
modprobed ipw2200, put it into monitor mode, used tshark a while to
monitor, then I stopped tshark, "ifconfig eth2 down" and finally
"rmmod ipw2200", and voila:

3f378b6844 net: pass kern to net_proto_family create function
The generic __sock_create function has a kern argument which allows the
security system to make decisions based on if a socket is being created by
the kernel or by userspace.  This patch passes that flag to the
net_proto_family specific create function, so it can do the same thing.

15ddd2d0ef bnx2x: Enable FC when parallel-detect is used
When parallel detect is used, flow-control is set to the
req_fc_auto_adv instead of none.

Motive: when 577xx is FC configuration is set to AUTO, while LP speed
is set to FORCE mode and FC to force RX/TX, link would come up using
parallel detect, and the FC will be set to NONE since FC capabilities
were not negotiated, although the LP is setting FC to force RX/TX.

22402529df virtio_net: rename driver struct to please modpost
Commit

	3d1285b (move virtnet_remove to .devexit.text)

introduced the first reference to __devexit in struct virtio_driver
virtio_net which upset modpost ("Section mismatch in reference from the
variable virtio_net to the function .devexit.text:virtnet_remove()").

Fix this by renaming virtio_net to virtio_net_driver.

37b12dd2b0 rtl8187: Fix kernel oops when device is removed when LEDS enabled
As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187
USB stick, or unloading the driver rtl8187 using rmmod will cause a
kernel oops.  There are at least two forms of the failure, (1) BUG:
Scheduling while atomic, and (2) a fatal kernel page fault. This
problem is reported in Bugzilla #14539.

This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2,
thus it is technically a regression; however, bisection did not locate
any faulty patch. The fix was found by comparing the faulty code in
rtl8187 with p54usb.  My interpretation is that the handling of work
queues in mac80211 changed enough to the LEDs to be unregistered
before tasks on the work queues are cancelled. Previously, these
actions could be done in either order.

(Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the
code is the same in 2.6.31, so this may be a candidate for 2.6.31.x.

3306ef642a rt2800usb: use rt2x00usb_register_multiwrite() to set key entries
Since struct hw_key_entry is 32-bytes large and is smaller than
CSR cache size (which is 64-bytes large) we can use the standard
rt2x00usb_register_multiwrite() helper to set key entries.

This cleanup is a part of preparations for later code unification.

5ed176e1c4 mac80211: make ieee80211_find_sta per virtual interface
Since we have a TODO item to make all station
management dependent on virtual interfaces, I
figured I'd start with pushing such a change
to drivers before more drivers start using the
ieee80211_find_sta() API with a hw pointer and
cause us grief later on.

For now continue exporting the old API in form
of ieee80211_find_sta_by_hw(), but discourage
its use strongly.

5b9482dda6 mwl8k: pci BAR mapping changes
Map BAR0 as well, as we need to write to it during init on some chips.

Also, if BAR0 is a 64bit BAR, the register BAR becomes BAR2, so try
mapping BAR2 if mapping BAR1 fails.

3d76e82c95 mwl8k: use cond_resched() when loading firmware blocks
Since each firmware block takes on the order of several hundred usec
to upload to the hardware, using msleep in the inner loop would make
the firmware loading process take a lot more time than just doing
busy-waiting like we do now.  But if we keep the busy-waiting, we can
at least add a cond_resched() to the inner loop so that we give other
tasks a chance to run while the firmware is being loaded.

77165d8809 mwl8k: enforce FIF_BCN_PRBRESP_PROMISC when no STA interfaces are active
When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS
filter so that we'll only see packets destined for our BSS.  But if no
STA interfaces have been configured, we would end up passing the BSSID
00:00:00:00:00:00 into the POST_SCAN command, which actually disables
the hardware's BSS filter, as it's not a valid BSSID.

Fix this by passing in 01:00:00:00:00:00 instead (the criterion is
that the OUI part of the BSSID must be nonzero), and add comments to
explain what PRE_SCAN and POST_SCAN do.

d5e308457e mwl8k: fix multicast address filter programming
mwl8k's ->prepare_multicast() currently just enables reception of
all multicast packets, which is somewhat ineffective.

Fix this by either disabling all multicast RX, enabling multicast
RX according to the multicast address filter table, or enabling all
multicast RX, depending on whether ->prepare_multicast() was given
any multicast addresses and whether the hardware multicast address
filter table is large enough to fit all requested addresses.

88de754ad5 mwl8k: minor transmit quiescing rework
Minor changes to the transmit quiescing logic:
- Clarify the locking rules for ->tx_wait: only the holder of fw_mutex
  can wait for the TX path to become idle, but tx_wait itself is read
  and cleared by the TX reclaim tasklet under tx_lock.
- Inline mwl8k_txq_busy() in its callers.
- There's no need to kick the transmitter again in
  mwl8k_tx_wait_empty(), since it will have been kicked when the
  packets currently in the TX ring were added to it.
- If the TX ring didn't drain in time, run mwl8k_scan_tx_ring() after
  reading priv->pending_pkts without dropping tx_lock in between.
