Subject: [dpdk-dev] [PATCH] rte_reciprocal: make arg to rte_reciprocal_divide_u64 const
Date: Thu, 21 Mar 2019 12:59:10 -0700	[thread overview]
Message-ID: <20190321195910.11140-1-stephen@networkplumber.org> (raw)
Message-ID: <20190321195910.NgDHd_Vt1PdZHIprQvEVeSbVUjgu5806XmPjVFExhGQ@z> (raw)

The divisor is not modified here. Doesn't really matter for optimizaton
since the function is inline already; but helps with expressing
intent.
