I've also seen hangs, in both RX and TX, but mostly RX.

The response to failing to alloc an skb is a bit weak in mwifiex, we
noted this on OLPC XO-4 with the 8787.  You can see more about the
problem and some local fixes in our private branch:

http://dev.laptop.org/git/olpc-kernel/log/?h=arm-3.5

http://dev.laptop.org/ticket/12694 (kernel 3.5)

I did backport the latest mwifiex at the time, but it did not fix the
issue, so I dug into it more.
