From 6ba07449ed54297cd45d6f46d4d6fcff5b571a42 Mon Sep 17 00:00:00 2001 From: Xueming Li Date: Mon, 23 Apr 2018 20:33:04 +0800 Subject: [PATCH] net/mlx5: cleanup tunnel checksum offloads Once tunnel packet type(RTE_PTYPE_TUNNEL_xxx) identified, PKT_RX_IP_CKSUM_XXX and PKT_RX_L4_CKSUM_XXX represent checksum result of inner headers, outer L3 and L4 header checksum are always valid as soon as tunnel identified. If no tunnel identified, PKT_RX_IP_CKSUM_XXX and PKT_RX_L4_CKSUM_XXX represent checksum result of outer L3 and L4 headers.
