Subject: [dpdk-dev] [PATCH 1/4] eal: use sizeof to avoid a double use of a define
Date: Tue, 27 Feb 2018 15:46:27 +0100 [thread overview]
Message-ID: <20180227144630.29613-2-olivier.matz@6wind.com> (raw)
In-Reply-To: <20180227144630.29613-1-olivier.matz@6wind.com>
Only a cosmetic change: the *_LEN defines are already used
when defining the buffer. Using sizeof() ensures that the length
stays consistent, even if the definition is modified.
