[PATCH net 1/2] bnxt_en: Disable aRFS if running on 212 firmware
From: Michael Chan <michael.chan@broadcom.com>
Date: 2021-08-15 20:16:00
Subsystem:
broadcom bnxt_en 50 gigabit ethernet driver, networking drivers, the rest · Maintainers:
Michael Chan, Pavan Chebbi, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
212 firmware broke aRFS, so disable it. Traffic may stop after ntuple
filters are inserted and deleted by the 212 firmware.
Fixes: ae10ae740ad2 ("bnxt_en: Add new hardware RFS mode.")
