Subject: Fix network-bridge ifup problem when bridge has no IP address.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~13714
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=d1abeffc818dee0e049525ccc6b3940680eef2e2;p=xen.git

Fix network-bridge ifup problem when bridge has no IP address.

When we want to setup a bridge without a ip address, function
do_ifup will not activate the bridge.

We should make the bridge active, then vif-bridge can work on the
bridge.
