[ipxe-devel] [ipxe] Adoptation of IPv6 from gPXE (#6)

[Anton D. Kachalov]

 - Add "accept-ra" setting to manage RA autoconfiguration.
 - Added IPv6 net_driver to send Router Solicitation when network brought up.
 - Added RDNSS option support. Only first IP accepted.
 - Minor fixes as mentioned below.

I will test it also on real network with multiple RAs, real v6 DNS and real hardware.

> Michael, would it be fine to accept multiple RAs but allow to set/edit only one manual IPv6? Other IPv6 address could be seen via "route" command. Otherwise, is there any suggestions to have multiple edit like:

>  ......... 1 -> "2a02:6b7:0:c32::d5/64 via 2a02:6b7:0:c32::"
