Viktor Mihajlovski a8fbbf1db7 s390: set DHCP client architecure id for netboot
Setting the client architecture DHCP option to 0x001f (s390 Basic) [1]
allows the DHCP server to return a s390-specific bootfile if wanted.
DHCP servers not configured for the option (or not yet recognizing the
option value) will continue to work as they have done before.
