Subject[RFC PATCH 01/11] phy: core add phy_set_netif_mode() api
Date
Add new API phy_set_netif_mode(struct phy *phy, phy_interface_t mode) and
new PHY operation callback .set_netif_mode() which intended to be implemnte
by PHY drivers which supports Network interrfaces mode selection. Both
accepts phy_interface_t vlaue as input parameter.
