offload_flags has been introduced to indicate encap status of each interface.
An interface can encap offload at runtime, or if it has some extra limitations
it can simply override the flags, so it's more flexible to check offload_flags
in Tx path.

2.18.0
It is currently limited to AP interfaces. 3-address mode STA interface
can either work by adding IEEE80211_OFFLOAD_ENCAP_ENABLED back into
vif->offload_flags, but just note that this breaks 4-address mode.
