It exposes the outer tunnel information to userspace, which was previously lost when it was translated into a port number. This makes it possible to implement things like multicast learning and simply the kernel module. In most cases there was not much wildcarding going on in the tunnel lookup, so the change should not affect the kernel flow table size. _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
