Subject: [dpdk-dev] [PATCH 09/38] net/sfc: use NIC min number of Tx descs instead of define
Date: Thu, 7 Feb 2019 16:29:14 +0000 [thread overview]
Message-ID: <1549556983-10896-10-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1549556983-10896-1-git-send-email-arybchenko@solarflare.com>
From: Igor Romanov <igor.romanov@oktetlabs.ru>
Min limit is not common for all NIC families. Use the variable from
NIC configuration instead of deprecated define.
