Subject: net/axgbe: check max SIMD bitwidth
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2b11056d1ef079d44844df2e6568ced372574e4e;p=dpdk.git

net/axgbe: 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.
