Subject: [net-next 13/15] ixgbe: ixgbe_atr() should access udp_hdr(skb) only for UDP packets

From: Sowmini Varadhan <sowmini.varadhan@...cle.com>

Commit 9f12df906cd8 ("ixgbe: Store VXLAN port number in network order")
incorrectly checks for hdr.ipv4->protocol != IPPROTO_UDP
in ixgbe_atr(). This check should be for "==" instead.
