It is obviously good for userspace to know up front which
interface modes a given piece of hardware might support (even
if adding such an interface might fail later because of
concurrency issues), so let's make cfg80211 aware of that.
For good measure, disallow adding interfaces in all other
modes so drivers don't forget to announce support for one mode
when they add it.

* No code changes...
* Split hw.c to multiple files for better maintenance and add some documentation on each file
code is going to grow soon (eeprom.c for example is going to get much stuff currently developed
on ath_info) so it's better this way.
* Rename following functions to maintain naming scheme:
ah_setup_xtx_desc -> ah_setup_mrr_tx_desc
(Because xtx doesn't say much, it's actually
a multi-rate-retry tx descriptor)
ath5k_hw_put_tx/rx_buf - > ath5k_hw_set_tx/rxdp
ath5k_hw_get_tx/rx_buf -> ath5k_hw_get_tx/rxdp
(We don't put any "buf" we set descriptor pointers on hw)
ath5k_hw_tx_start -> ath5k_hw_start_tx_dma
ath5k_hw_start_rx -> ath5k_hw_start_rx_dma
ath5k_hw_stop_pcu_recv -> ath5k_hw_stop_rx_pcu
(It's easier this way to identify them, we also
have ath5k_hw_start_rx_pcu which completes the
set)
ath5k_hw_set_intr -> ath5k_hw_set_imr
(As in get_isr we set imr here, not "intr")
* Move ath5k_hw_setup_rx_desc on ah->ah_setup_rx_desc so we can
include support for different rx descriptors in the future
* Further cleanups so that checkpatch doesn't complain
(only some > 80 col warnings for eeprom.h and reg.h as usual
due to comments)
Tested on 5211 and 5213 cards and works ok.

The allocated RX buffer size was 64 bytes bigger than the PCI mapped
size with no good reason. If the packet was actually using the buffer up
to its limit and if the last 64 bytes of the buffer crossed 4KB boundary
then an unmapped PCI page was accessed. The fix is to use only one
parameter for the buffer size - there is no need to differentiate
between the buffer size and the PCI mapping size since the extra 64
bytes can actually be used by the FW to align the Ethernet payload to
64 bytes.

This patch "iwlwifi: do not use GFP_DMA in iwl_tx_queue_init" removes
GFP_DMA from allocation tx command buffers. GFP_DMA allows allocation
only for memory under 16M which causes allocation problems
suspend/resume flows.
Using kmalloc is temporal solution and some consistent/coherent
allocation schema will be more correct. Since iwlwifi hardware
supports 64bit address this solution should work on x86 (32 and

This patch is a W/A for the TSF sync issue in IBSS merging. HW is not
capable to sync TSF (it's constantly little behind). This creates
constant IBSS merging upon reception of each beacon, adding and removing
station which in turn creates above 50% packet loss and thus dramatically
degrade the throughput. The W/A simply stops the driver from declaring it
has a reliable TSF value and thus eliminates IBSS merging.

Checksum generation is an attribute of our hardware TX queues, not TX
descriptors. We previously used a single queue and turned checksum
generation on or off as requested through ethtool. However, this can
result in regenerating checksums in raw packets that should not be
modified. We now create 2 hardware TX queues with checksum generation
on or off. They are presented to the net core as one queue since it
does not know how to select between them.
The self-test verifies that a bad checksum is unaltered on the queue
with checksum generation off.

net/xfrm: Use an IS_ERR test rather than a NULL test
ath9: Fix ath_rx_flush_tid() for IRQs disabled kernel warning message.
ath9k: Incorrect key used when group and pairwise ciphers are different.
rt2x00: Compiler warning unmasked by fix of BUILD_BUG_ON
mac80211: Fix debugfs union misuse and pointer corruption
wireless/libertas/if_cs.c: fix memory leaks
orinoco: Multicast to the specified addresses
iwlwifi: fix 64bit platform firmware loading
iwlwifi: fix apm_stop (wrong bit polarity for FLAG_INIT_DONE)
iwlwifi: workaround interrupt handling no some platforms
iwlwifi: do not use GFP_DMA in iwl_tx_queue_init
net/wireless/Kconfig: clarify the description for CONFIG_WIRELESS_EXT_SYSFS
net: Unbreak userspace usage of linux/mroute.h
pkt_sched: Fix locking of qdisc_root with qdisc_root_sleeping_lock()
ipv6: When we droped a packet, we should return NET_RX_DROP instead of 0
This patch addresses an issue with the locking order. ath_rx_flush_tid()
uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211.
As node clean up is still pending with ath9k and this problematic portion
of the code is expected to change anyway, thinking of a proper fix may not
be worthwhile. So having this interim fix helps the users to get rid of the
kernel warning message.
Pasted the kernel warning message for reference.

Updating sc_keytype multiple times when groupwise and pairwise
ciphers are different results in incorrect pairwise key type
assumed for TX control and normal ping fails. This works fine
for cases where both groupwise and pairwise ciphers are same.
Also use mac80211 provided enums for key length calculation.

A "Set" to a sign-bit in an "&" operation causes a compiler warning.
Make calculations unsigned.
[ The warning was masked by the old definition of BUILD_BUG_ON() ]
Also remove __builtin_constant_p from FIELD_CHECK since BUILD_BUG_ON
no longer permits non-const values.

The leak in if_cs_prog_helper() is obvious.
It looks a bit as if not freeing "fw" in if_cs_prog_real() was done
intentionally, but I'm not seeing why it shouldn't be freed.

When multicasting the driver sets the number of group addresses using
the count from the previous set multicast command. In general this means
you have to set the multicast addresses twice to get the behaviour you
want.
If we were multicasting, and reduce the number of addresses we are
multicasting to, then the driver would write uninitialised data from the
stack into the group addresses to multicast to.
Only write the multicast addresses we have specifically set.

GFP_DMA is not necessary for the iwlwifi hardware and it can cause
allocation failures and/or invoke the OOM killer on lots of systems.
