From 1eaae5198e0db1f523fa3432ded69247aa33bf20 Mon Sep 17 00:00:00 2001 From: Alan Brady Date: Thu, 5 Oct 2017 14:53:41 -0700 Subject: [PATCH] i40e: convert i40e_phy_type_to_ethtool to new API We are still largely using the old ethtool API macros. This is problematic because eventually they will be removed and they only support 32 bits of PHY types. This overhauls i40e_phy_type_to_ethtool to use only the new API. Doing this also allows us to provide much better support for newer 25G and 10G PHY types which is included here as well. The remaining usages of the old ethtool API will be addressed in other patches in the series.
