[PATCH 1/1] net: add support to parse the NIS domain for the dhcp options

[Charles Hardin <ckhardin@gmail.com>]

There is code in the bootp parsing for NIS domain and add the
same support for the dhcp options as well. This allows the same
usage of the data when the dhcp command is used in the boot
command.
