From: Didier Pallard <didier.pall...@6wind.com>
According to Table 7-38: Valid Fields by Offload Option
of Intel ? 82599 10 GbE Controller Datasheet,
L4LEN field is not needed for L4 XSUM computation by the hardware.
So remove l4_len from tx_offload_mask in ixgbe_set_xmit_ctx
function used to build the context transmitted to the hardware.
