Commit 3f5a2a713a zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed. This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example). We don't want SMB or CMB to change during this
operation.
Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

This implements 64 bit statistics support and fixes races when reading
counter values. The PHY counters can only be accessed 16 bits at a time,
so they are subject to carry races.
NB:
* TX/RX counters are maintained in software because the the hardware packet count
is only a 32 bit value.
* Error counters are really only 32 bit.
* Old 32 bit counter fields in dev->stats still used for some
software counters

Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition. However, 64-bit MIPS configurations
are not detected reliably either.
This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.

The sky2 driver uses the legacy PCI power management, so it has to do
some PCI-specific things in its ->suspend() and ->resume() callbacks,
which isn't necessary and should better be done by the PCI
sybsystem-level power management code. Moreover, it uses
device_set_wakeup_enable() incorrectly (that function should be
used when the WoL setting is changed rather than during suspend).

When changing ring size, we free all memory including status block
memory. If we're in INTA mode and sharing IRQ, the IRQ handler can
be called and it will reference the NULL status block pointer.
Because of the lockless design of the IRQ handler, there is no simple
way to synchronize and prevent this. So we avoid this problem by
freeing the IRQ handler before freeing the status block memory.

Linux would not connect to other router running old version Cisco IOS (12.0).
This is most likely a bug in that version of IOS, since it is fixed
in later versions. As a workaround this patch allows a module parameter
to be set to disable compressing the protocol ID.
See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979
RFC 1990 allows an implementation to formulate MP fragments as if protocol
compression had been negotiated. This allows us to always send compressed
protocol IDs. But some implementations don't accept MP fragments with
compressed protocol IDs. This parameter allows us to interoperate with
them. The default value of the configurable parameter is the same as the
current behavior: protocol compression is enabled. If protocol compression
is disabled we will not send compressed protocol IDs.
This is based on an earlier patch by Bob Gilligan (using a sysctl).
Module parameter is writable to allow for enabling even if ppp
is already loaded for other uses.

Add a new variable to keep track of the currently configured tx power. Before
max_pwr was re-used for keeping the maximum allowed power as well as the
current configuration. Doing a min() on it allows you to lower the txpower, but
how would you be able to make it higher again?
This patch fixes that by adding a new variable ah_cur_pwr which is used instead
of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check
if we are within the limits.
Another problem fixed by this patch is that it avoids setting a zero txpower
when things are initialized first and the current power is not yet set.

ath9k supports its own set of virtual wiphys, and it uses
the mac80211 idle notifications to know when a device needs
to be idle or not. We recently changed ath9k to force idle
on driver stop() and on resume but forgot to take into account
ath9k's own virtual wiphy idle states. These are used internally
by ath9k to check if the device's radio should be powered down
on each idle call. Without this change its possible that the
device could have been forced off but the virtual wiphy idle
was left on.

The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed
the code that sets the PAPRD rate masks to use only either the HT20 mask
or the HT40 mask. This is wrong, as the hardware can still use HT20 rates
even when configured for HT40, and the operating channel mode does not
affect PAPRD operation.
The register for the HT40 rate mask is applied as a mask on top of the
other registers to selectively disable PAPRD for specific rates on HT40
packets only.
This patch changes the code back to the old behavior which matches the
intended use of these registers. While with current cards this should not
make any practical difference (according to Atheros, the HT20 and HT40
mask should always be equal), it is more correct that way, and maybe
the HT40 mask will be used for some rare corner cases in the future.

When rfkill is enabled, ath9k_hw unnecessarily configured the baseband to
turn off based on GPIO input, however that code was hardcoded to GPIO 0
instead of ah->rfkill_gpio.
Since ath9k uses software rfkill anyway, this code is completely unnecessary
and should be removed in case anything else ever uses GPIO 0.

To improve aggregation length, there should not be more than two fully formed
A-MPDU frames in the hardware queue. To ensure this, the code checks the tx
queue length before forming new A-MPDUs. This can reduce the throughput (or
maybe even starve out A-MPDU traffic) when too many non-aggregated frames are
in the queue.
Fix this by keeping track of pending A-MPDU frames (even when they're sent out
as single frames), but exclude rate control probing frames to improve
performance.
