Subject: [PATCH net-next 06/10] r8169: replace longer if statements with switch statements
Date: Wed, 2 May 2018 21:39:52 +0200	[thread overview]
Message-ID: <ea66cc59-a460-0853-abe6-e2282afd4505@gmail.com> (raw)
In-Reply-To: <2c7cae9e-d989-8529-7209-5a271242ce39@gmail.com>

Some longer if statements can be simplified by using switch
statements instead.
