New Revision: 262683
URL: http://svnweb.freebsd.org/changeset/base/262683
Log:
Set all of the ports into the same vlangroup; there's only one vlangroup
(pvid=1) and we already configure them to send to other ports.
Setting pvid=portnum would mean that there were separate vlangroups
for each ports, but 'leaking' into other ports. The result? All port
traffic flooded to all other port traffic.
Tested:
* DB120, AR9344 + AR8327 switch
