It looks like the passed in if_softc is pointing to a struct ifvlan instead of the expected struct ieee80211_vap Looking at vlan_output(), I wonder if the parents ifnet context should be used when calling if_output()? I've attached a patch to show what I mean. -- You are receiving this mail because: You are the assignee for the bug.
