Re: [lwip-users] netif_is_up ?

[David Haas]

Hi Jani,

I'm not sure when this change was made, but you now have to explicitly 
make a call to bring your interface up.

My initialization looks like this:

   netif_add(&netif, &ipaddr, &netmask, &gw, NULL, mcf5272fecif_init, 
tcpip_input);
   netif_set_default(&netif);
   netif_set_up(&netif);

Since I am not using DHCP right now.

I have'nt looked at any of the code, but I would suppose PPP also uses 
netif_set_up() and netif_set_down() when the interface goes up and down.

David.
