[ovs-dev] [patch_ports (rebased) 1/4] ofproto-dpif: Scope revalidation state to dpif_backers.

Wed Jan 23 20:51:10 UTC 2013
Before this patch, the "need_revalidate" flag and the
"revalidate_set" tag_set where maintained separately for each
ofproto. This won't work in future patches when a flow table
change in one ofproto can require revalidation in another entirely
separate ofproto. For this reason, this patch scopes these flags
to the dpif_backers.
