mac80211: rework tx encapsulation offload API
The current API (which lets the driver turn on/off per vif directly) has a number of limitations: - it does not deal with AP_VLAN - conditions for enabling (no tkip, no monitor) are only checked at add_interface time - no way to indicate 4-addr support In order to address this, store offload flags in struct ieee80211_vif (easy to extend for decap offload later). mac80211 initially sets the enable flag, but gives the driver a chance to modify it before its settings are applied. In addition to the .add_interface op, a .update_vif_offload op is introduced, which can be used for runtime changes. If a driver can't disable encap offload at runtime, or if it has some extra limitations, it can simply override the flags within those ops. Support for encap offload with 4-address mode interfaces can be enabled by setting a flag from .add_interface or .update_vif_offload.
