Subject: bridge: Populate interface status/statistics as soon as a port is added.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1101a0b47;p=openvswitch

bridge: Populate interface status/statistics as soon as a port is added.

Currently there's a lag of up to five seconds before the status and statistics
columns in the Interface table are populated when a port is first added to a
bridge. This may confuse systems that expect those columns to be populated
right away.

Bug #6145.
