Partial diff between the 1efipxe branch and master

     /* Re-use the existing local port number */
     udata.StationPort = socket->net.efi.localport;
 
-    udata.UseDefaultAddress = TRUE;
+    if (efi_net_def_addr) {
+       udata.UseDefaultAddress = TRUE;
+    } else {
+       udata.UseDefaultAddress = FALSE;
+       memcpy(&udata.StationAddress, &IPInfo.myip, sizeof(IPInfo.myip));
+       memcpy(&udata.StationAddress, &IPInfo.netmask, sizeof(IPInfo.netmask));
+    }
     memcpy(&udata.RemoteAddress, &ip, sizeof(ip));
     udata.RemotePort = port;
     udata.TimeToLive = 64;

So don't worry about "manual"  :-)

Waiting on an updated version of the firmware is however not an option.

O, these are the moments where I realize again how lucky we are
with a bootloader that is libre software.

Yes, collaboration is the way to succes.
