These patches are on top of Michael Chang's bootp6 code (which we also really
need so it would be great if those could go in as well). At Facebook we have
ipv6 only clusters that we need to be able to provision over the network. The
current grub2 support for ipv6 is broken in a few ways. The routing stuff
needed to be reworked to handle talking to an ipv6 router properly. I tried to
not change the code too much in order to make sure I didn't regress the ipv4
support.
Thanks for your feedback, that's very encouraging to me. :-)
The patch is still in review and need to solve some issues addressed by
Andrei. I was distracted by some other stuff later and my own server
hosted virtual machine to develope and test ipv6 was accidently broken
by system update of virtualization package. The major changes that cause
the failure seems to be qemu changes to enable ipxe UEFI option rom
which somehow did not provide ipv6 support in it's UNDI driver, along
with some other issues in edk2/ovmf itself.
Anyway boop6 patches seems to be innocent to the new problem I have and
can continue the work by not loading iPXE UEFI option rom from qemu. To
whom who may be interested here is libvirt guest config I use to disable
option rom and use edk2's network stack.

I will continue on working on the patches and follow through review for
the patch set with upstream.
