Subject: [PATCH net-next v4 10/11] stmmac: intel: interface switching support for EHL platform
From: Choong Yong Liang <yong.liang.choong@...el.com>
'intel_get_pcs_neg_mode' and 'intel_config_serdes' was provided to
handle interface mode change for EHL platform.
Modphy register lane was provided to configure serdes on interface
mode changing.
