      ath9k_hw: Optimize ath9k_hw_ar9287_set_board_values · 79d7f4bc
      由 Sujith 提交于 
      Rather than doing a series of RMWs, calculate the
value to be written to the register in question and
do a single REGWRITE. This improves bringup time.

This depends on the analog_shiftreg configuration option,
which is currently buggy. For AP mode, a delay of 100us
has to be the default. For station mode, this knob has to
be enabled on a per-case basis, though it is a little
unclear on when to enable a delay. This can be fixed later though.

      drivers/net: Remove unnecessary returns from void function()s · a4b77097
      由 Joe Perches 提交于 
      This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

It also does not remove null void functions with return.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

with some cleanups by hand.

Compile tested x86 allmodconfig only.

      ath9k: RX stucks during heavy traffic in HT40 mode. · dd8b15b0
      由 Senthil Balasubramanian 提交于 
      Running iperf along with p2p traffic on both TX and RX side then
stop one side, then stop the other side, then start it up again,
eventually the STA gets into a mode that it can not pass data at
all.

A hardware workaround for invalid RSSI can make FIFO write pointer
to jump over read pointer, causing RX data corruption and repeated
DMA. Both TX and RX works fine when the workaround is disabled.

To replace the original hardware work around, software looks for
frames with post delimiter CRC error and mark the RSSI invalid so
that the upperlayer will not use the RSSI associated with this
frame. So disable the hardware workaround by updating the appropriate
registers.
