It was sent to the rc tree, don't worry this is stuff I fix up.

Stephen's note is to help ensure it is fixed properly, does the change
look OK? It looks like this when applied (I changed Stephen's slightly)

static int rxe_udp_encap_recv(struct sock *sk, struct sk_buff *skb)
{
struct udphdr *udph;
struct rxe_dev *rxe;
struct net_device *ndev = skb->dev;
struct rxe_pkt_info *pkt = SKB_TO_PKT(skb);

/* takes a reference on rxe->ib_dev
* drop when skb is freed
*/
rxe = rxe_get_dev_from_net(ndev);
if (!rxe && is_vlan_dev(rdev))
rxe = rxe_get_dev_from_net(vlan_dev_real_dev(ndev));
if (!rxe)
goto drop;
