Subject: bonding: Update the link status on the bond fake interface.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c6303ea11b76880306c12885a1007c516e40d1df;p=openvswitch

bonding: Update the link status on the bond fake interface.

Brings the fake bond interface up and down to match our notion of
whether the bond is currently active.  This solves an issue where
XenCenter would always show the bond as disconnected.

Bug #1703
