[PATCH net 2/4] bnxt: disable napi before cancelling DIM
From: Jakub Kicinski <kuba@kernel.org>
Date: 2021-08-11 19:32:45
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
napi schedules DIM, napi has to be disabled first,
then DIM cancelled.
Noticed while reading the code.
Fixes: 0bc0b97fca73 ("bnxt_en: cleanup DIM work on device shutdown")
Fixes: 6a8788f25625 ("bnxt_en: add support for software dynamic interrupt moderation")
