From: Jingjing Wu Date: Thu, 4 Dec 2014 15:40:23 +0000 (+0800) Subject: i40e: setup flow director only if enabled X-Git-Tag: spdx-start~9989 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e689a63caa4ebd43367b67601384066234525fb5;p=dpdk.git i40e: setup flow director only if enabled In order not to affect the FVL's performance by default setting, this patch moves the flow director initialization from i40e_pf_setup to i40e_dev_configure according to the mode in fdir configure info. Then the resources used for flow director will be only setup if it is enabled.
