cfg80211: don't drop p2p probe responses
Commit 0a35d36 ("cfg80211: Use capability info to detect mesh beacons") assumed that probe response with both ESS and IBSS bits cleared means that the frame was sent by a mesh sta. However, these capabilities are also being used in the p2p_find phase, and the mesh-validation broke it. Rename the WLAN_CAPABILITY_IS_MBSS macro, and verify that mesh ies exist before assuming this frame was sent by a mesh sta. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.
