Subject: [dpdk-dev] [PATCH] ixgbe: remove useless fields in tx_offload on TCP
checksum request

From: Didier Pallard <redacted>

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.
