From 8109e1232b3e5322415a9b5e09951617c5fae277 Mon Sep 17 00:00:00 2001 From: Catherine Sullivan Date: Wed, 4 Jun 2014 08:45:24 +0000 Subject: [PATCH] i40e/i40evf: Add new HW link info variable an_enabled and function update_link_info Add a new variable, hw.phy.link_info.an_enabled, to track whether autoneg is enabled. Also add a new function update_link_info that will update that variable as well as calling get_link_info to update the rest of the link info. Also add get_phy_capabilities to support this.
