[En-Nut-Discussion] dhcp problem

[András Szemző]

Hi all,

I'm using at91sam7x with onboard ethernet with GPRS primary/backup PPP  
device. Everything works fine, I have just one problem.
If I configure the ethernet device with DHCP, I must wait with PPP  
device register until DHCP configure the ethernet, becouse
NutIpOut will send broadcast request on a wrong device (PPP). I can  
solve this by modify NutIpOutput

...
/*
   * Broadcasts are sent on all network interfaces.
    */
  if (dest == 0xffffffff) {

         memset(ha, 0xff, sizeof(ha));

	 for (dev = nutDeviceList, rc = 0; dev && rc == 0; dev = dev- 
 >dev_next) {

		nif = dev->dev_icb;
	 	
		if (dev->dev_type == IFTYP_NET && nif->if_type == IFT_ETHER) {
...

but in this case udp broadcast messages will by tied to ethernet  
device only.

Is there a better solution for this problem?
