From: Roopa Prabhu <ro...@cumulusnetworks.com>
This patch is a follow up to the recently added
'static' fdb option.
It introduces a new option 'dynamic' which adds
dynamic fdb entries with NUD_REACHABLE.
$bridge fdb add 00:01:02:03:04:06 dev eth0 master dynamic
$bridge fdb show
00:01:02:03:04:06 dev eth0
This patch also documents all fdb types. Removes 'temp'
from usage message since it is now replaced by 'static'.
'temp' still works and is synonymous with static.
