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.

As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with unresolved symbols. This patch moves ATH_COMMON selection to the common part for both ATH9K and ATH9K_HTC Signed-off-by: Vladimir Kondratiev Signed-off-by: John W.

We have already accounted for this in NETFRONT_SKB_CB(skb)->pull_to so use that instead. Fixes WARN_ON from skb_try_coalesce.
