43b7b314f6 mac80211: Learn about mesh portals from multicast traffic
Mesh portals proxy traffic for nodes external to the mesh.  When a
proxied frame is received by a mesh interface, it should update its mesh
portal table.  This was only happening for unicast frames.  With this
change we also learn about mesh portals from proxied multicast frames.

878283f198 wl1251: use ieee80211_rx_ni()
Because of SPI and SDIO wl1251 does everything in a workqueue, including
calling ieee80211_rx() which should be called with bottom halves disabled.
An error message is emitted because of this:

NOHZ: local_softirq_pending 08

Fix this by using ieee80211_rx_ni().

d0f63b2021 wl1271: fix endianess issues
We were not handling endianess correctly.  The wl1271 chip runs on
little-endian values.  This patch makes sure that all the communication with
the wl1271 firmware is done in little-endian by using cpu_to_le* and
le*_to_cpu where appropriate.

Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.

This fixes a few sparse warnings, such as these:

e5e2647fd6 ath5k: use noise calibration from madwifi hal
This updates ath5k to calibrate the noise floor similar to the
way it is done in the madwifi hal and ath9k.  Of note:

- we start NF measurement at the same time as AGC calibration,
  but do not actually read the value until the periodic (long)
  calibration
- we keep a history of the last few values read and write the
  median back to the hardware for CCA
- we do not complain if NF calibration isn't complete, instead
  we keep the last read value.

2b60100bf0 wl1271: Add structure for firmware configuration values
In order to make the firmware configuration more manageable, collect
hardcoded configuration values into one data structure, and set default values
there.

Add the SoftGemini BT/WLAN coex paramters into the config structure.

2cc8d4db9d wl1271: Workaround for reference clock setting on boot.
If the 38.4MHz reference clock is configured to the firmware, it crashes
on boot. Configuring an experimental 38.4MHz in XTAL mode allows the
firmware to boot, and everything appears to work.

2f301227a1 iwlwifi: use paged Rx
This switches the iwlwifi driver to use paged skb from linear skb for Rx
buffer. So that it relieves some Rx buffer allocation pressure for the
memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for
Rx buffer. Due to the trailing skb_shared_info in the skb->data,
alloc_skb() will do the next order allocation, which is 16K bytes. This
is suboptimal and more likely to fail when the system is under memory
usage pressure. Switching to paged Rx skb lets us allocate the RXB
directly by alloc_pages(), so that only order 1 allocation is required.

It also adjusts the area spin_lock (with IRQ disabled) protected in the
tasklet because tasklet guarentees to run only on one CPU and the new
unprotected code can be preempted by the IRQ handler. This saves us from
spawning another workqueue to make skb_linearize/__pskb_pull_tail happy
(which cannot be called in hard irq context).

Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb
for all the management frames and software decryption or defragmentation
required data frames before handed to mac80211. For all the other frames,
we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211
to handle them properly.

ae751bab9f wl1271: remove unnecessary joins and join only when the bssid changes
We were using the join command to change some settings when the stack asked
us to do it.  In many cases they were not needed (and could cause potential
problems), so they were removed.  In other cases there are ACX commands that
can be used instead of using join to reconfigure.

0535d9f4f0 wl1271: use acx_rx_config instead of join when updating filters
We shouldn't use a join command to change the filter settings while
associated.  The right way to do it is to use ACX_RX_CFG.

7462141787 wl1271: Remove outdated SPI functions
With the change to the new firmware, there was a change to firmware memory
partitioning. Along with that change, the translation of all partitions was
unified, and separate functions for reg and mem access became unnecessary.

Cleanup the unnecessary functions.
