mac80211: disable BSSID filtering for mesh interfaces (a3c9aa51) · Commits · 戴 / test

Mesh interfaces are currently opened with the FIF_ALLMULTI rx filter flag set, however there is no BSSID in mesh so BSSID filtering should be disabled by setting the FIF_OTHER_BSS flag as well. Also explicitly call ieee80211_configure_filter for mesh. Signed-off-by:
