Subject: [dpdk-dev] [PATCH 31/37] net/sfc/base: use simpler code to check hash algorithm type
Date: Mon, 10 Sep 2018 10:33:30 +0100 [thread overview]
Message-ID: <1536572016-18134-32-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1536572016-18134-1-git-send-email-arybchenko@solarflare.com>
From: Ivan Malov <Ivan.Malov@oktetlabs.ru>
The API which is used to list supported hash flags verifies
hash algorithm choice before writing the output. This check
is based on a switch() statement which has only two options
and no distinctive actions to be conducted for each of them.
Use simpler code instead of switch() to improve readability.
