From fe723dff0fa4181ddb8116e72bc67d00d4239cb6 Mon Sep 17 00:00:00 2001 From: Manish Awasthi Date: Thu, 16 Mar 2017 16:16:17 -0700 Subject: [PATCH] liquidio: fix wrong information about link modes reported to ethtool Information reported to ethtool about link modes is wrong for 25G NIC. Fix it by checking for presence of 25G NIC, checking the link speed reported by NIC firmware, and then assigning proper values to the ethtool_link_ksettings struct.
