Subject: [dpdk-dev] [PATCH 05/38] net/sfc/base: remove min define for number of Tx descs
Date: Thu, 7 Feb 2019 16:29:10 +0000 [thread overview]
Message-ID: <1549556983-10896-6-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>
EF100/Riverhead has different min limit. So, this limit should
be a part of NIC config, not define common for all NIC families.
Define maximum Tx descriptor number for Siena in the same way as
minimum for consistency.
