Subject: [dpdk-dev] [PATCH] net/failsafe: limit device capabilities to really supported
Date: Wed, 29 Aug 2018 08:45:36 +0100 [thread overview]
Message-ID: <1535528736-31325-1-git-send-email-arybchenko@solarflare.com> (raw)
From: Igor Romanov <Igor.Romanov@oktetlabs.ru>
Failsafe driver does not support any device capabilities yet.
Make fs_dev_infos_get() consider default ones to limit advertised
device capabilities to really supported instead of unconditional
inheritance from sub-devices.
Fixes: cac923cfea47 ("ethdev: support runtime queue setup")
