New Revision: 220743
URL: http://svn.freebsd.org/changeset/base/220743
Log:
Fix IPv6 ND. After r219562 we in nd6_ns_input() were erroneously always
passing the cached proxydl reference (sockaddr_dl initialized or not) to
nd6_na_output(). nd6_na_output() will thus assume a proxy NA. Revert to
conditionally passing either &proxydl or NULL if no proxy case desired.
Tested by: ipv6gw and ref9-i386
