[PATCH] Updated udp.c to use real client ip and subnetmask values if on local subnet
from: Jeff Sloan <jeff_sloan at selinc.com>
Based on commit: 9314e330
Setting UseDefaultAddress to TRUE uses invalid StationAddress and
SubnetMask values. This is in a network with a local TFTP/MTFTP server. If
the server is local, on the same subnet, UseDefaultAddress is set to false
and the client ip and subnetmask are loaded, otherwise set
UseDefaultAddress to TRUE. This is added to
