[PATCH 00/14] Facebook's netbooting patches

[Josef Bacik]

I've recently fixed up a bunch of new issues and rebased onto todays master so I
figured I'd send our current backlog.  So first the new patches that you guys
haven't seen yet

[PATCH 10/14] dns: poll card between each dns request
[PATCH 11/14] dns: reset data->naddresses for every packet we receive
[PATCH 12/14] icmp6: use default interface as the route interface
[PATCH 13/14] bootp: don't add multiple interfaces for the same
[PATCH 14/14] net: add interfaces when we open a card

Basically DNS would not wait long enough for AAAA records to come back and would
corrupt memory if it got multiple records in different packets.  I've also made
it so we try to prefer our dhcp interface when possible and to make sure we're
not adding duplicate interfaces if we run net_bootp/6 multiple times.

The rest of the patches have already been posted before and have been updated to
reflect the reviews that where given.

The first 3 patches

[PATCH 01/14] Added net_bootp6 command
[PATCH 02/14] UEFI IPv6 PXE support
[PATCH 03/14] Use UEFI MAC device as default configured by net_bootp6

Are not mine, they are Michael Chang's and I've kept the authorship and
everything set properly to reflect that.

With these patches we've been provisioning tens of thousands of boxes in ipv4
only, mixed ipv4/ipv6, and ipv6 only environments with very small failure rates
(around 2%).  They are solid and being used in production on a wide variety of
hardware, both EFI and legacy BIOS.  If you like you can pull them from my
github

Any comments or review would be greatly appreciated.  We are keen to get these
patches upstream so we can start doing continual testing with the grub2 master
branch.  Thanks,

Josef
