[PATCH net-next] net: dsa: microchip: split adjust_link() in phylink_mac_link_{up|down}()

Codrin Ciubotariu
2020-07-02T09:54:49Z

The DSA subsystem moved to phylink and adjust_link() became deprecated in
the process. This patch removes adjust_link from the KSZ DSA switches and
adds phylink_mac_link_up() and phylink_mac_link_down().
