New Revision: 222143
URL: http://svn.freebsd.org/changeset/base/222143
Log:
The statically configured (permanent) ARP entries are removed when an
interface is brought down, even though the interface address is still
valid. This patch maintains the permanent ARP entries as long as the
interface address (having the same prefix as that of the ARP entries)
is valid.
