Subject: [PATCH net-next v1 8/8] amd-xgbe: Remove the XGBE_LINK state bit

The XGBE_LINK bit is used just to determine whether to call the
netif_carrier_on/off functions. Rather than define and use this bit,
just call the functions. The netif_carrier_ok function can be used in
place of checking the XGBE_LINK bit in the future.
