                        if (be16_to_cpup((u16 *) skb->data) != ETH_P_ARP) {
                                ipoib_warn(priv, "Unicast, no %s: type %04x, QPN %06x "
                                           IPOIB_GID_FMT "\n",
                                           skb->dst ? "neigh" : "dst",
                                           be16_to_cpup((u16 *) skb->data),
                                           be32_to_cpup((u32 *) phdr->hwaddr),
                                           IPOIB_GID_ARG(*(union ib_gid *) (phdr->hwaddr + 4)));
                                dev_kfree_skb_any(skb);
                                ++priv->stats.tx_dropped;
                                goto out;
                        }

So it looks like 0x806 is being put in the QPN rather than type on the remote
machine which is an x86_64 (Opteron) machine.

Not sure whether this is related to what causes the oops or not.
