Subject: Only log unprocessed packets in the controller if debugging enabled.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f4da69c169f4a69d8563ebf8dbe8934748fb969;p=openvswitch

Only log unprocessed packets in the controller if debugging enabled.

Otherwise OFP_FLOW_EXPIRED messages tend to swamp the console after
a while.
