X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cd6c524e9e0b5ad8ce52bc3b4a3a1e272e3a8410;p=linux-beck.git mac80211: Do not request FIF_BCN_PRBRESP_PROMISC for HW scan. ieee80211_configure_filter code used local->scanning as a boolean value when it was a bit mask. Bits SCAN_COMPLETED, SCAN_ABORTED should not set FIF_BCN_PRBRESP_PROMISC filter. SCAN_HW_SCANNING should not set FIF_BCN_PRBRESP_PROMISC either, as there is no explicit filter configuration request from scan code. If a driver requires FIF_BCN_PRBRESP_PROMISC mode during HW scanning, it's up to the driver to temporary enable it. Similar mistake was fixed also in ieee80211_hw_config (power configuration code).
