New Revision: 226451
URL: http://svn.freebsd.org/changeset/base/226451
Log:
The IPv6 code was influx at the time of r196865 due to the L2/L3
separation rewrite changes. r196865 was committed to fix a scope
violation problem in the following test scenario:
box-1# ifconfig em0 inet6 2001:db8:1:: prefixlen 64 anycast
box-1# ifconfig em1 inet6 2001:db8:2::1 prefixlen 64
box-2# ifconfig re0 inet6 2001:db8:1::6 prefixlen 64
em0 and re0 are on the same link.
box-2# ping6 2001:db8:1::
PING6(56=40+8+8 bytes) 2001:db8:1::6 --> 2001:db8:1::
the ICMPv6 response should have a source address of em1, which
is 2001:db8:2::1, not the link-local address of em0.
That code is no longer necessary and breaks the IPv6-Ready logo
testing, so revert it now.
