Subject: netdev: Add 'netdev' parameter to netdev_add_router().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0efaf4b50c99bfdc255a27bb55312744feb34cc6;p=openvswitch

netdev: Add 'netdev' parameter to netdev_add_router().

When there is the possibility of multiple classes of netdevs,
netdev_add_router() needs to know which of these to use, so it needs a
"struct netdev *" parameter.
