Hello,

We configure external switch in u-boot.
The configuration is through mdio (cpu is mac and switch is phy).

But in Linux we rather not implement any communication in mdio to
switch, but it means that we then don't have the information of link
state.

Is it possible to force in Linux (by default in startup) Ethernet
connectivity (netif_carrier_on, netif_wake_queue) even if there is no
information of real link state ?

Thank you,
ranran
