Between 3.16 and 3.18 we have only those rt2x00 changes: cfd9167 rt2x00: do not align payload on modern H/W 664d6a7 wireless: rt2x00: add new rt2800usb device 01f7fee rt2800: correct BBP1_TX_POWER_CTRL mask ac0372a rt2x00: support Ralink 5362. 9baa3c3 PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use 6a06e55 wireless: rt2x00: add new rt2800usb devices d4150246 drivers/net/wireless/rt2x00/rt2x00dev.c: remove null test before kfree df6e633 rt2x00: Use dma_zalloc_coherent 19dcb76 rt2x00: do not initialize BCN_OFFSET registers ddb4055 rt2x00: change order when stop beaconing 88ff2f4 rt2x00: change default MAC_BSSID_DW1_BSS_BCN_NUM ba08910 rt2x00: change beaconing setup on RT2800 283dafa rt2x00: change beaconing locking 57eaeb6 net: wireless: rt2x00: rt2x00mac.c: Cleaning up uninitialized variables They could be reverted, even on top of 3.19-rc7, instead of doing full bisection. But this could be also mac80211 issue, then bisection will be necessary to figure out this bug.
