[PATCH net 4/4] bnxt_en: fix LRO/GRO_HW features in ndo_fix_features callback
From: Michael Chan <michael.chan@broadcom.com>
Date: 2022-08-22 15:10:09
Subsystem:
broadcom bnxt_en 50 gigabit ethernet driver, networking drivers, the rest · Maintainers:

From: Vikas Gupta <vikas.gupta@broadcom.com>
LRO/GRO_HW should be disabled if there is an attached XDP program.
BNXT_FLAG_TPA is the current setting of the LRO/GRO_HW. Using
BNXT_FLAG_TPA to disable LRO/GRO_HW will cause these features to be
permanently disabled once they are disabled.
