We believed that some valid SNAP frames were being marked as invalid.
In fact this is not the case and no workaround is needed.

Currently the board initialisation includes 2 delays of 1 second each.
Usually it is unnecessary to wait that long, so check before doing so.
Correct some of the comments and log messages while we're here.

efx_test_loopback() used "|" to combine the results of the RX and TX
phases. If both phases fail with different error codes, this results
in a bogus error code.

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.

This patch rewrites the TX power recalculation algorithms to scale better
with changed enviromnent. If there's low
TX traffic, the power will be checked against the desired values
every 60 seconds.
If there is high TX traffic, the check is redone every 2 seconds. This improves
the reaction times a lot and confuses the rate control less.
It will also reduce the time it initially takes to tune to a new TX power
value. With the old algorithm it could take about 30 to 45 seconds to settle to
a new power value. This will happen in about two to four seconds now.

This patch implements a dynamic "ops" based PHY API.
This is needed in order to conveniently support future PHY types
to avoid the "switch"-hell.
This patch does not change any functionality. It just moves lots
of code from one place to another and adjusts it for the changed
data structures.

Instead of using the PLCP flag to indicate if the
signal value is plcp or the bitrate we should add
a new flag to mark the bitrate type explicitely.
This is usefull when new types are added later for

Some hardware configuration registers such as antenna and channel configuration
can only be written when the radio is enabled. Previously, we didn't consider
this, so some configuration items could be set inconsistently after reenabling
the radio. This patch changes the config() handler to only reprogram the
hardware when the radio is enabled. Configuration changes that are made while
the radio is off are postponed until the radio is switched back on. We also
leave the radio turned off during initialization and only enable it when
requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag,
because the device is now guaranteed to be completely initialized when brought
up by mac80211.

Some of the flags should be accessed atomically to
prevent race conditions. The flags that are most important
are those that can change often and indicate the actual
state of the device, queue or queue entry.
The big flag rename was done to move all state flags to
the same naming type as the other rt2x00dev flags and
made sure all places where the flags were used were changed. ;)
Thanks to Stephen for most of the queue flags updates,
which fixes some of the most obvious consequences of the
race conditions. Among those the notorious:
rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.
rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.
rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.

Ever wondered why the signal was so bad with p54 compared to madwifi, or intel?
Well, if you have revision 1 rssi calibration curve points in your EEPROM, then wonder no more.
The firmware wants a extra 1 byte padding for every curve point. But someone forgot to put
them into the EEPROM's data structure...
So now, big question: what happens when we blindly "memcpy" these data points?

Use TX control flag IEEE80211_TX_CTL_ASSIGN_SEQ as a request to update
the seq# for the frames. This will likely require some further cleanup
to get seq# correctly for Beacons vs. other frames and also potentially
for multiple BSSes. Anyway, this is better than ending up sending out
most frames with seq# 0.

This change moves ath9k to use mac80211-generated Beacon frames instead
of trying to allocate a single Beacon frame and then update it. In
addition, the remaining ath_skb_{map,unmap}_single() wrapper calls are
replaced with direct pci_{map,unmap}_single() calls in beacon.c. Power
save buffering for multicast/broadcast frames is not yet converted to
use mac80211-style (frames to be buffered inside mac80211, not in
driver).
