Message-Id: <1424854720-18825-4-git-send-email-jeffrey.t.kirsher@intel.com> Date: Wed, 25 Feb 2015 00:58:28 -0800 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Carolyn Wyborny <carolyn.wyborny@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 03/15] i40e: Add method to keep track of current rxnfc settings From: Carolyn Wyborny <carolyn.wyborny@...el.com> This patch adds a struct to the VSI struct to keep track of rxnfc settings done via ethtool. Without this patch, the device can only list the options available, not the current settings and this is not clear to the user. Without current settings, the available settings never changing looks like a bug. Also update the copyright year.
