From 533866b12cce484994163b1e201778cbac4c04c5 Mon Sep 17 00:00:00 2001 From: "Porsch, Marco" Date: Wed, 24 Feb 2010 09:53:13 +0100 Subject: [PATCH] mac80211: fix PREQ processing and one small bug 1st) a PREQ should only be processed, if it has the same SN and better metric (instead of better or equal). 2nd) next_hop[ETH_ALEN] now actually used to buffer mpath->next_hop->sta.addr for use out of lock.
