Kalle Valo cdd1e9a91e wl1251: use __dev_alloc_skb() on RX
RX is handled in a workqueue therefore allocating for GFP_ATOMIC
is overkill and not required.

Kalle Valo b5a167942c wl1251: reduce ELP wakeup timeout
The original TI driver uses 100 ms timeout ELP wakeup timeout, better
to use the same. Otherwise problems with wakeup might get unnoticed.

Luciano Coelho 17d7265c75 wl1271: fix the inetdev notifier callback return values
The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return
NOTIFY_* instead.  Now we use NOTIFY_DONE when we didn't handle the event or
NOTIFY_OK when we have handled it.

For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or
NOTIFY_OK, because it ignores the return value of the call to
blocking_notifier_call_chain().  But the notify.h header says that
NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be
the right way to do it.

Kalle Valo 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().

Luciano Coelho 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:

if we down the interface and only do a soft reset before bringing

the firmware, enabling a second call to wl1251_boot() to succeed
without a hard reset.

Johannes Berg 3ac64beecd mac80211: allow configure_filter callback to sleep
Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.

A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

Kalle Valo f26b32ed4b wl1251: hack to disable filters for fixing association
Commit 9cef8737 "mac80211: fix managed mode BSSID handling" broke
association in wl1251, most probably because the driver configured
the bssid filter incorrectly. Workaround this by disabling filter
altogether. This needs to be fixed properly soon.

Bob Copeland b5ed9c1b6f wl1251: make irq handling interface specific
In SDIO, the host driver requests the IRQ and invokes a callback to the
card driver.  This differs from SPI, so the relevant code needs to be
interface-specific.  This patch pushes the irq code down into _spi.c
and _sdio.c, and adds enable/disable callbacks.

This fixes the following warning:
