Subject: bridge: Omit alerts on the cfm_remote_opstate column.
X-Git-Tag: sliver-openvswitch-1.8.90-0~1^2~7
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=4104aaf1b850692cf8db2d05a82f872f6c127925;hp=c6100d92142bc3dd325180cb4e10553eb4341731;p=sliver-openvswitch.git

bridge: Omit alerts on the cfm_remote_opstate column.

This column should be write only, otherwise every call to update it
has to make a trip to the database.  Since this column is updated
every time through the run loop as part of refresh_instant_stats(),
this patch fixes a significant performance degradation.
