Hi,

You need to read PHY_BSR register (1) and check bit 3 ... this is the link
status. This is what I am doing in a task.
The reason for doing the above is that a PHY with RMII has no link interrupt
and the simplest way is to read the
basic status register.
Do you have a fully functional driver and initialize code that works for you ?

I haveKSZ8081RNACA as phy that has to be polled (interrupt signal is not
routed)
In LWIP documentation I read:
- netif_set_link_up(struct netif *netif)
This is the hardware link state; e.g. whether cable is plugged for wired
Ethernet interface. This function must be called even if you don't know
the current state. Having link up and link down events is optional but
DHCP and IPv6 discover benefit well from those events.
- netif_set_up(struct netif *netif)
This is the administrative (= software) state of the netif, when the
netif is fully configured this function must be called.
So I understand that netif_set_link_up() has to be called from phy driver? and
what about netif_set_up()?
best regads
