From: Stephen Hemminger Date: Tue, 23 Apr 2019 16:53:33 +0000 (-0700) Subject: net/ring: avoid hard-coded length X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1af59f5ddacaf9287f81e20b49207f28ecbb0e56;p=dpdk.git net/ring: avoid hard-coded length Don't hard code string length in two place; use sizeof() instead. Ring name should use RTE_RING_NAMESIZE.
