4cd24eaf0c net: use netdev_mc_count and netdev_mc_empty when appropriate
This patch replaces dev->mc_count in all drivers (hopefully I didn't miss
anything). Used spatch and did small tweaks and conding style changes when
it was suitable.

42c4568a4a ath9k: add a workaround for ack timeout issues
Adding support for setting the coverage class in some cases broke
association and data transfer, as it overwrote the initial ACK timeout
value from the initvals with a smaller value.
I don't know why the new value works in 5 GHz (matches the initval
there), but not in 2.4 GHz (initvals use 64us here), so until the
problem is fully understood, the value should be increased again.

2ac2927a95 ath5k: use correct packet type when transmitting
The hardware needs to know what type of frames are being
sent in order to fill in various fields, for example the
timestamp in probe responses (before this patch, it was
always 0).  Set it correctly when initializing the TX
descriptor.

21b2d8bd2f iwlwifi: Send broadcast probe request only when asked to
When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

ed56a3f15a iwlwifi: Add chain_noise support for 6050
Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset).  As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

40e6fa829a libertas: don't retry commands
Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.

Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

This code could be extended to actually do the

only pretend. Since hwsim was written to ease

permanently.

b6c3f5be7c b43: Fix throughput regression
Commit c7ab5ef9bc entitled "b43: implement
short slot and basic rate handling" reduced the transmit throughput for
my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling
portion is OK, the problem is in the short slot handling.

Prior to this change, the short slot enable/disable routines were never
called. Experimentation showed that the critical part was changing the
value at offset 0x0010 in the shared memory. This is supposed to contain
the 802.11 Slot Time in usec, but if it is changed from its initial value
of zero, performance is destroyed. On the other hand, changing the value
in the MMIO register corresponding to the Interframe Slot Time increased
performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic
improvement of the transmit rate from 5.3 to 19.0 Mb/s.

Other changes in the patch include removal of the magic number for the
MMIO register, and allowing the slot time to be set for any PHY operating
in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.

f643e51d71 ath: make gcc check format arguments of ath_print(), fix all misuses
Numeric channel is hard to get, so it won't be printed.  Replace Mhz
with MHz on the affected lines and add commas as needed.

d3a571971e iwlwifi: iwl_power_update_mode always hold mutex
iwl_power_update_mode expects to be called with mutex held, for example to
protect priv->vif. Only one caller currently does not do this, fix this.
Also, add a comment to iwl_power_update_mode to indicate this requirement.
