Commit Message

Grygorii Strashko Oct. 8, 2018, 11:49 p.m. UTC 
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.
