From: Guoyang Zhou Date: Wed, 11 Nov 2020 06:33:37 +0000 (+0800) Subject: net/hinic/base: add message check for command channel X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=cb99500de915040339f294b6ad2fc8edb4085b19;p=dpdk.git net/hinic/base: add message check for command channel In the command channel, a message may has several fragments, and the several fragments should have same message id. To prevent problems, this check is added.
