From c17af95a19e30c8d89eb96ceca99f60474ca2ac4 Mon Sep 17 00:00:00 2001 From: Murphy Yang Date: Thu, 3 Dec 2020 07:50:30 +0000 Subject: [PATCH] net/i40e: fix L4 checksum flag When tunneled packet received that inner L4 checksum value is correct, the test_pmd output log shows 'ol_flags' value is 'PKT_RX_L4_CKSUM_UNKNOWN', but expected value is 'PKT_RX_L4_CKSUM_GOOD'. If the inner l4 checksum is correct, mark the 'PKT_RX_L4_CKSUM_GOOD' flag to 'l3_l4e_flags' for sse and 'l3_l4_flags_shuf' for avx2 to ensure that the 'ol_flags' can match correct flags.
