Subject: ethdev: ensure same name size for device and ethdev
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=48d8675c9cff887f96e960183e7b408829870b46;p=dpdk.git

ethdev: ensure same name size for device and ethdev

rte_device->name copied into eth_dev->name, right now size is same for
both but the requirement is not clear.

This patch highlights the relation without changing actual sizes.
