Hi all:
    I have a question about VXLAN pkt transmition. When ovs encaps a pkt with tunnel header, it will lookup the tnl arp cache(by tnl_neigh_lookup), but if the arp cache is empty, the bridge will send an arp request out. And at the same time, this pkt which need to be tunnel encaped is dropped, am I right ? I want to know if there is a so called pkt cache machanism when arp cache is null.

Thanks 
Timo
