mac80211: fix suppressing probe responses in ad-hoc mode
The commit "mac80211: reply to directed probes in IBSS" changed ad-hoc specific code to respond to unicast probe requests, even if drv_tx_last_beacon returns false, however due to confusion over the meaning of the IEEE80211_RX_RA_MATCH flag, it also unconditionally enabled responding to multicast probe requests. Fix this by explicitly checking for a multicast destination address instead. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
