The handling of tx descriptors for beacons can be simplified by updating
write_tx_desc implementations of each driver to write directly to the
queue entry descriptor instead of to a provided memory area.
This is also a preparation for further clean ups where descriptors are
properly reserved in the skb instead of fiddling with the skb data
pointer.

Where possible, write the tx descriptor words from start to end, to
follow a logical ordering of words.
Where this is not possible (in rt2400pci, rt2500pci and rt61pci) add
a comment as to why word 0 needs to be written last.

The buffer address descriptor word is not part of the TXINFO structure
needed for beacons. The current writing of that word for beacons is
therefore an out-of-bounds write.
Fix this by only writing the buffer address descriptor word for TX
queues.

Remove the double swapping of the descriptor data structure, instead
keep it little-endian (native format of the eeprom data), and byteswap
on access.
This allows sparse to verify endian access to the eeprom struct.

The ready message from the target could be processed
before the host HW init has completed. In this case,
htc_process_target_rdy() would assume the target has timed
out, when it hasn't. Fix this by checking if the target

These changes include:
* For PAPRD, the TXRF3.capdiv5G, TXRF3.rdiv5G and TXRF3.rdiv2G
are set to 0x0, the TXRF6.capdiv2G is set to 0x2 for all
three chains.
* The d2cas5G/d3cas5G/d4cas5G was updated to 4/4/4 in lowest_ob_db
Tx gain table.
* To improve DPPM, three parameters were updated (Released from Madhan):
1. RANGE_OSDAC is set to 0x1 for 2G, 0x0 for 5G
2. offsetC1 is set to 0xc
3. inv_clk320_adc is set to 0x1
* To reduce PHY error(from spur), cycpwr_thr1 and cycpwr_thr1_ext
are increased to 0x8 at 2G.
* The 2G Rx gain tables are updated with mixer gain setting 3,1,0.

Jumbo frames are not supported, and if they are seen it is likely
a bogus frame so just silently discard them instead of warning on
them all time. Also, instead of dropping them immediately though
move the check *after* we check for all sort of frame errors. This
should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.
Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be
happening.
This is reported quite often and if it fills the logs then this
needs to be addressed and to avoid spurious reports.
