From: Andrew Evans Date: Mon, 17 Jan 2011 23:37:13 +0000 (-0800) Subject: bridge: Store status of physical network interfaces in Interface table. X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e210037edde788ffcc03497019903dadd6eadcfa;p=openvswitch bridge: Store status of physical network interfaces in Interface table. New columns in Interface table: admin_state, link_state, link_speed, duplex, mtu. New keys in status map in Interface table: driver_name, driver_version, firmware_version.
