Subject: [PATCH] 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.

Subject: [PATCH] mac80211: optimize station connection monitor
Calling mod_timer for every rx/tx packet can be quite expensive.
Instead of constantly updating the timer, we can simply let it run out
and check the timestamp of the last ACK or rx packet to re-arm it.

Subject: [PATCH] mac80211: swap NEED_TXPROCESSING and HW_80211_ENCAP tx
flags
In order to unify the tx status path, the hw 802.11 encapsulation flag
needs to survive the trip to the tx status call.
Since we don't have any free bits in info->flags, we need to move one.
IEEE80211_TX_INTFL_NEED_TXPROCESSING is only used internally in mac80211,
and only before the call into the driver.

Subject: [PATCH] mac80211: skip encap offload for tx multicast/control
packets
This simplifies the checks in the encap offload tx handler and allows using
it in cases where software crypto is used for multicast packets, e.g. when
using an AP_VLAN.
