[PATCH 0/7] ath10k: rework rx path

This patchset unifies rx path. Instead of
branching for A-MSDU and MSDU cases a single
codepath is introduced.

This yields:

   text    data     bss     dec     hex filename
  14068       0       0   14068    36f4 before/htt_rx.o
  13308       3       0   13311    33ff after/htt_rx.o

I haven't measured any Rx performance loss in my
setup but I may be biased. In theory this could
reduce i-cache pressure and improve Rx throughput
on CPU contrained systems by a few mbps.

This patchset serves two purposes though:
 - clean up and unify the Rx path a bit
 - make it possible to reuse code more easily in
   the future

Michal Kazior (7):
  ath10k: start using sk_buff_head
  ath10k: simplify Rx loop
  ath10k: refactor htt->rx_confused
  ath10k: unify rx undecapping
  ath10k: remove unused function argument
  ath10k: use rx descriptor for ppdu status extraction
  ath10k: report rx rate and signal for fragmented Rx
