tg3_start_xmit() makes the wrong assumption for TSOV6 that skb->head
doesnt include any payload data.
if (skb_is_gso_v6(skb))
hdr_len = skb_headlen(skb) - ETH_HLEN;
This is not true anymore after commit f07d960df3 (tcp: avoid frag
allocation for small frames)
We should instead use : skb_transport_offset(skb) + tcp_hdrlen(skb)
Its also true for IPv4
