Comment (by [EMAIL PROTECTED]):
Changes made in the patch:
- Fix some double locking issues from process context/tasklet to interrupt
- Convert IEEE80211_NODE_LOCK to a spinlock instead of a rw_spinlock
- Convert IEEE80211_BEACON_LOCK/IEEE80211_UAPSD_LOCK to IEEE80211_LOCK
(locks same thing, less confusing)
- Redefined #defines to avoid ambiguity and standardize them properly
- Used lockflags in local context only
- ath_tx_timeout calls ath_reset instead of ath_init to avoid semaphore
locking
