Subject: distributor: check max SIMD bitwidth
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=eec67546aa4b4e5569d1e37f1e89a242a64f0062;p=dpdk.git

distributor: check max SIMD bitwidth

When choosing a vector path to take, an extra condition must be
satisfied to ensure the max SIMD bitwidth allows for the CPU enabled
path.
