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
