Subject: [065/151] mac80211: Fixed bug in mesh portal paths

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Javier Cardona <javier@...ybit.com>

commit 5d618cb81aeea19879975cd1f9a1e707694dfd7c upstream.

Paths to mesh portals were being timed out immediately after each use in
intermediate forwarding nodes.  mppath->exp_time is set to the expiration time
so assigning it to jiffies was marking the path as expired.
