[syslinux] [PATCH] Updated udp.c to use real client ip and subnetmask values if on local subnet

[Patrick Masotta]

>>>
 Pseudo code:  Using the most recently used handle (the one holding
 Pxebc by default), attempt to create a service binding.  If unsuccessful, 
 hunt for a handle that provides the target service
 binding and matches the MAC address.
 
 Best case, it's 1 binding attempt.  Worst case it's about N+1.

I see; on fail you fall back getting all handles again by "bguid".
This approach would have no benefit if there are consecutive alternative 
binding (UDP/TCP) but that's unlikely to happen.

Best,
Patrick
