From e9cd6721460c59dc289d169b5d411bf8b9cef57a Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 20 Sep 2017 15:52:13 -0700 Subject: net: ethtool: Add back transceiver type commit 19cab8872692960535aa6d12e3a295ac51d1a648 upstream. Commit 3f1ac7a700d0 ("net: ethtool: add new ETHTOOL_xLINKSETTINGS API") deprecated the ethtool_cmd::transceiver field, which was fine in premise, except that the PHY library was actually using it to report the type of transceiver: internal or external. Use the first word of the reserved field to put this __u8 transceiver field back in. It is made read-only, and we don't expect the ETHTOOL_xLINKSETTINGS API to be doing anything with this anyway, so this is mostly for the legacy path where we do: ethtool_get_settings() -> dev->ethtool_ops->get_link_ksettings() -> convert_link_ksettings_to_legacy_settings() to have no information loss compared to the legacy get_settings API.
