vxlan-udp-recv function lookup vxlan_sock struct on every packet recv by using udp-port number. we can use sk->sk_user_data to store vxlan_sock and avoid lookup. This commit also allows us to get rid of socket hash table. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com>
