Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.
