SVN rev 218676 on 2011-02-14 08:14:06Z by hselasky
* Fix page fault caused by referring freed node.
While updating Tx stats, already freed node could be referred and cause
page fault. To avoid such panic, spool Tx stats in driver's softc. Then,
on every ratectl interval, grab node though ieee80211_iterate_nodes() and
update ratectl stats.
* Simplify some code in run_iter_func().
* Fix typo
* Use memset instead of bzero (hselasky @)
