Subject: [dpdk-dev] [PATCH v3 08/18] librte_acl: make scalar RT code to be more similar to vector one.
Date: Tue, 20 Jan 2015 18:40:57 +0000 [thread overview]
Message-ID: <1421779267-18492-9-git-send-email-konstantin.ananyev@intel.com> (raw)
In-Reply-To: <1421779267-18492-1-git-send-email-konstantin.ananyev@intel.com>
Make classify_scalar to behave in the same way as it's vector counterpart:
move match check out of the inner loop, etc.
That makes scalar and vector code look more identical.
Plus it improves scalar code performance.
