This patch series contains a few loosely related changes in mac80211
I did over the past few days:
* clarify use of TX status/RX callbacks
as per my previous mail, the irqsafe/non-irq-safe stuff
* safely free beacon in ieee80211_if_reinit
This is necessary for reentrancy reasons with ieee80211_beacon_get()
* split ieee80211_key_alloc
Preparation for RCU-ifying STA info, split key allocation into
allocation and insertion
* RCU-ify STA info structure access
Remove STA refcount and instead protect them by RCU
* split ieee80211_txrx_data
Mostly unrelated, split up txrx_data and flags into one struct for TX
and one for RX
* split sta_info_add
Split sta_info_add into _alloc and _link to resolve a few races and
allow GFP_KERNEL allocations in many cases (which was removed by the
RCU-ification patch)
* remove STA info's last_ack stuff
Remove some unused stats members
* clean up sta_info and document locking
Document and clean up the definition of struct sta_info and document
the locking (deficiencies)
I'd like to have somebody else look over these but I'm confident that the
changes do not, at least, introduce regressions.
