Subject: ofproto-dpif: Simplify invocation of send_packet().
X-Git-Tag: v1.4.0~84
X-Git-Url: http://git.onelab.eu/?a=commitdiff_plain;h=97d6520bea3b779d1acee7b1b2fd8ed60269078f;p=sliver-openvswitch.git

ofproto-dpif: Simplify invocation of send_packet().

All the callers already have the ofport handy, so they might as well just
pass it in directly.
