Subject: datapath: Allow datapath device MAC address to be changed while it is up.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a0b0a2cf1d130b8645ce3da6042c1bdc8a7c33b5;p=openvswitch

datapath: Allow datapath device MAC address to be changed while it is up.

vswitchd wants to do this, and I don't see a reason to disallow it.
