RE: RE : [lwip-users] Cleaning up my code and I was wondering....

[Julian Gardner [RSD]]

Found that one and I now have my code calling tcpip_callback( 
netif_set_link_up, netif); and tcpip_callback( netif_set_link_down, netif); 
depending on the link status from the chip.

Is this the correct way for getting the library UP, as i seem to have the 
link_up working now?

        netif_add( &smcif_if, &ipaddr, &netmask, &gw, NULL, smcIfinit, 
tcpip_input);
        netif_set_default( &smcif_if);

        if( e2Prom.ethernetSettings.dhcpActive )
        {
                dhcp_start( &smcif_if);
        }
        else
        {
                netif_set_up( &smcif_if);
        }

And now in my main tcp loop i wait for netif_is_up, and when this happens i can 
start my apps?
