   3 Subject: [PATCH] mac80211: check per vif offload_flags in Tx path
   4
   5 offload_flags has been introduced to indicate encap status of each interface.
   6 An interface can encap offload at runtime, or if it has some extra limitations
   7 it can simply override the flags, so it's more flexible to check offload_flags
   8 in Tx path.
