From 48a580c5df78b3addac6f57969167bb86c7428f5 Mon Sep 17 00:00:00 2001 From: Lance Richardson Date: Fri, 18 Dec 2020 15:28:37 -0500 Subject: [PATCH] net/bnxt: set correct checksum status in mbuf The setting of the mbuf ol_flags field for tunneled packets should be different depending upon whether DEV_RX_OFFLOAD_OUTER_* offloads are enabled. Initialize ol_flags mappings based on the receive offload configuration when the receive ring is initialized.
