Subject: Drop "send_openflow_skb: send failed: -3" warning.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bc96a226a91a588e255cbc697ba6318ee6bfb805;p=openvswitch

Drop "send_openflow_skb: send failed: -3" warning.

This message appeared in the normal course of OpenFlow usage when
a packet arrived on an OpenFlow interface and no secure channel
was running, or if packets arrived too fast for the secure channel
to process them.  It confused more people than it assisted, so drop
it.
