Hi,
-----Original Message----- From: dev [mailto:dev-bounces@dpdk.org] On Behalf Of David Marchand Sent: Thursday, October 29, 2015 4:48 PM To: dev@dpdk.org 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.
