Description Andrew Atrens 2012-04-04 16:00:09 UTC
If one has a FreeBSD AP and clients (like iPods and macbooks) that are
constantly going into/out-of power saving mode, the AP will leak mbufs
for fragmented packets added to the sleeping node's power saving queue.

Eventually (depending on activity, available kvm) the AP will run out of
mbuf/clusters and become incommunicado.

--Andrew

Fix: Here's my patch -

$ svn diff ieee80211_power.c
How-To-Repeat: See above.
