[PATCH net-next v1] net: netcp: remove call to netif_carrier_(on/off) for MAC to Phy interface

[Murali Karicheri]

Currently when interface type is MAC to Phy, netif_carrier_(on/off)
is called which is not needed as Phy lib already updates the carrier
status to net stack. This is needed only for other interface types

 - Fixed comment against initial version
 - Ok to apply this to net-next. So changed subject prefix to reflect the same
