Author: ae Date: Thu Oct 30 13:53:57 2014 New Revision: 273859 URL: https://svnweb.freebsd.org/changeset/base/273859 Log: MFC r272770: When tunneling interface is going to insert mbuf into netisr queue after stripping outer header, consider it as new packet and clear the protocols flags. This fixes problems when IPSEC traffic goes through various tunnels and router doesn't send ICMP/ICMPv6 errors.
