Jonas Gorski c3f251a317 mwl8k: don't overwrite regulatory settings on fw reload
Currently the caps are parsed on every firmware reload, causing any
channel flags to be cleared.
When there is a firmware to interface mode mismatch, the triggered
firmware reload causes a reset of the regulatory settings, causing all
channels to become available:

To prevent this, only parse the caps on the first firmware load during

them.

Ashok Nagarajan 8908c7d539 mwifiex: Trigger a card reset on reaching tx_timeout threshold
tx_timeout doesn't always lead to a cmd_timeout. There are
occurrences where cmd_timeout never gets triggered for a long
time and we encounter a kernel crash. In this patch, we track
the consecutive timeouts (tx_timeout_cnt). When tx_timeout_cnt
exceeds the threshold, trigger a card reset thereby avoiding a
kernel crash.

wake-on RX packets with TCP destination port 80
iw phy0 wowlan enable patterns 44+50

wake-on MagicPacket:
iw phy0 wowlan enable magic-packet

wake-on MagicPacket or patterns:
iw phy0 wowlan enable magic-packet patterns 12+00:11:22:33:44:55
  18+00:50:43:21

wake-on IPv4 multicast packets:

Avinash Patil f553e1aad7 mwifiex: modify skb->truesize for PCIE Rx
We allocate SKB buffers of 4K size to make sure that we process
RX AMSDU of 4K. So when skb->len is lesser than 4K; we should
modify skb->truesize. This resolves an issue where kernel has
allocated packets with 2K assumption and starts dropping packets
for large size data transfer.

This fix is already present for USB; extend it to PCIE.

Bob Copeland 4ba910db19 ath9k: simplify ATH_EP_RND
Remove the embedded branch to make the ATH_EP_RND macro a little
clearer.  The new version also generates better code, saving 24
bytes of text:

   text	   data	    bss	    dec	    hex	filename
  87858	   1641	     24	  89523	  15db3	ath9k_orig.ko
  87834	   1641	     24	  89499	  15d9b	ath9k_new.ko

Although neither version handles negative values particularly well,
the lone caller clamps all negative values to zero anyway.  I have
verified that the results are the same for the range of possible
positive rssi values.

Dan Carpenter 2dcc26e37c ray_cs: read past the end of the array
"translate" should either be set or disabled.  We also use it an
offset into the framing[] array when we're generating the proc
file.  Framing looks like this:

static const char *framing[] = { "Encapsulation", "Translation" }

So when we're setting translate we need to restrict the values to
either 1 or 0 or it can an out of bounds read.

Jiri Slaby 188741731c ath5k: cleanup channel to eprom_mode function
Stop returning negative values from ath5k_eeprom_mode_from_channel.
Yell loudly about that case in that function instead and return the
default/zero/mode A. This cleans up the callers, but needs to pass ah
down to ath5k_eeprom_mode_from_channel for ATH5K_WARN. For that
purpose we also need the declaration to be moved to ath5k.h.
