Subject: vport: Record and free packets on unattached ports.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f7cf2ff0b63dc76af9358282dcbe81e9433a94ae;p=openvswitch

vport: Record and free packets on unattached ports.

We throw away packets that are received on vports not attached to
a datapath but we are actually leaking them.  This records that an
error took place and frees the skb.
