Subject: [PATCH] Revert "net: phy: simplify phy_link_change arguments"
|
|
|
|
This reverts commit a307593a644443db12888f45eed0dafb5869e2cc.
|
|
|
|
This brings back the do_carrier flags used by the (hacky) next patch,
|
|
still required by target/linux/ramips/files/drivers/net/ethernet/ralink/mdio.c
