From 90e3012e94be0755a516f60f5339a2a08f4a7d0a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 18 Jun 2009 14:51:12 +0200 Subject: [PATCH] mac80211_hwsim: clean up the skb before passing it back We need to clean up the skb before we can copy it, this is required for proper operation since the socket it is still attached to could potentially live in a different network namespace or so.
