Original ipoib code had this:

        if (unlikely(skb->len > dev->mtu + INFINIBAND_ALEN)) {
                ipoib_warn(priv, "packet len %d (> %d) too long to send, dropping\n",
                           skb->len, dev->mtu + INFINIBAND_ALEN);
                ++priv->stats.tx_dropped;
                ++priv->stats.tx_errors;
                dev_kfree_skb_any(skb);
                return;
        }

so length is compared to mtu + encap length here.
