From: Olivier Matz Date: Tue, 24 Apr 2018 14:46:47 +0000 (+0200) Subject: use sizeof to avoid double use of a length define X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dec7b1884a555c941110526cc6cb9dfa08fd51b9;p=dpdk.git use sizeof to avoid double use of a length define 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.
