2013-04-26NFC: Move LLCP code to the NFC top level diirectorySamuel Ortiz
And stop making it optional. LLCP is a fundamental part of the NFC specifications and making it optional does not make much sense. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-04-23mwifiex: rework round robin scheduling of bss nodes.Andreas Fenkart
Rotate bss prio list, so the bss next to the one served, will come first in the list of bss' with equal priority. This way we pick bss nodes in a round robin fashion. Using list rotation instead of a cur ptr simplifies iteration to calling list_for_each_entry. List rotation is done via list_move, where the head itself is temporarily removed and then re-inserted after the bss just served.

2013-04-23mwifiex: replace ra_list_curr by list rotation.Andreas Fenkart
After a packet is successfully transmitted, ra list is rotated, so the ra next to the one transmitted, will be the first in the list. This way we pick the ra' in a round robin fashion. This significantly simplifies iteration in mwifiex_wmm_get_highest_priolist_ptr to a call to list_for_each_entry. List rotation is done via list_move, where the head itself is temporarily removed and then re-inserted after the item just transferred.

2013-04-23ath9k: Use lockless variants for the RX fifo queueSujith Manoharan
The RX fifo can be accessed from the common tasklet or it can be reaped/cleaned when RX is stopped, which is done when doing a reset or channel change - this happens in process context. Since it is ensured that there are no pending tasklets when stopping RX and cleaning the FIFO, there is no need to use SKB queue functions which take internal locks.
