Subject: [dpdk-dev] [PATCH]i40e: move the fdir_setup from dev_init to dev_configure
Date: Thu, 4 Dec 2014 23:40:23 +0800 [thread overview]
Message-ID: <1417707623-25777-1-git-send-email-jingjing.wu@intel.com> (raw)
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.
