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.
