New Revision: 255021
URL: http://svnweb.freebsd.org/changeset/base/255021
Log:
Prevent the full restart cycle every time arge_start() is called. Only
(re)start the interface when it is down. This change fix a race with
BOOTP where the response packet is lost because the interface is being
reset by a netmask change right after send the packet.
