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.

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.

The function brcmf_proto_hdrpush() increases the header space and
fills in the protocol header fields. One field is the data offset
which is currently fixed to zero meaning the data follows right
after the header. The parameter is added to determine the actual
start of data. This will be used for firmware signalling.

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.

"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.
