net: dhcp: allow to set transmitted vendor id
For net boot setups it is useful to submit boot params like server or
bootfile over dhcp. To distinguish barebox from e.g. pxe machines,
a custom vendor id can be sent in dhcp discover/request messages.
E.g. the ISC dhcp server can be configured with
| if substring(option vendor-class-identifier,0,8) = "barebox:" {
| next-server 192.168.3.24;
| server-name "192.168.3.24";
| option tftp-server-name "192.168.3.24";
| option root-path = concat("/srv/sysroots/by-mac/",
| binary-to-ascii (16, 8, "-", substring (hardware, 1, 6)));
| }
to sent boot params which are valid for barebox hosts only.
