Subject: vport: Record and free packets on unattached ports.
X-Git-Tag: v1.0.0~24

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.
