[BNX2]: Fix TSO problem with small MSS.
Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU at the source and we still need to process it as a TSO packet. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com> for reporting the problem. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
