2013-06-24cw1200: Fix up a large pile of sparse warningsSolomon Peachy
Most of these relate to endianness problems, and are purely cosmetic. But a couple of them were legit -- listen interval parsing and some of the rate selection code would malfunction on BE systems. There's still one cosmetic warning remaining, in the (admittedly) ugly code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI transfers, but many SPI controllers only operate 8 bits at a time. If there's a cleaner way of handling this, I'm all ears.

2013-06-24ath9k: fix queue depth accounting in ath_tx_txqaddbufFelix Fietkau
ath_tx_txqaddbuf assumes that all the linked buffers in the queue passed to it are part of the same A-MPDU or MPDU. The CAB queue rework violates this assumption, which can cause the internal queue depth to go negative. Fix this by increasing the counter for all slots of [bf, bf->bf_lastbf] Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the same condition twice. The problem was found using cppcheck-1.49, and the proper fix was verified against the pre-mac80211 version of the code.

2013-06-17mwifiex: fix memory corruption when unsetting multicast listDaniel Drake
When trying to unset a previously-set multicast list (i.e. the new list has 0 entries), mwifiex_set_multicast_list() was calling down to mwifiex_request_set_multicast_list() while leaving mcast_list.num_multicast_addr as an uninitialized value. We were arriving at mwifiex_cmd_mac_multicast_adr() which would then proceed to do an often huge memcpy of mcast_list.num_multicast_addr*ETH_ALEN bytes, causing memory corruption and hard to debug crashes. Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast list is provided. Similarly, fix up the logic in mwifiex_request_set_multicast_list() to unset the multicast list that was previously sent to the hardware in such cases.

2013-06-17wlcore: fix occasional AP TX stop after recoveryVictor Goldenshtein
The fw_status wasn't zeroed during allocation, resulting in uninitialized var usage, and finally causing AP traffic stop after recovery. The wrong value in fw_status_2->counters.tx_lnk_free_pkts led to a bad lnk->allocated_pkts calculation in wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return FALSE (lnk->allocated_pkts > thold). This eventually blocked the link in wlcore_tx_work_locked(), as wl1271_skb_dequeue() continuously returned NULL. Fix it by zeroing wl->fw_status_1/2 during allocation.
