From: Helin Zhang Date: Tue, 3 Nov 2015 15:40:28 +0000 (+0800) Subject: i40e: enlarge the number of supported queues X-Git-Tag: spdx-start~8152 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=705b57f82054;p=dpdk.git i40e: enlarge the number of supported queues It enlarges the number of supported queues to hardware allowed maximum. There was a software limitation of 64 per physical port which is not reasonable.
