[PATCH 00/10] Support UEFI HTTP boot with IPv6 and DNS

[Michael Chang]

This patch series extends GRUB's network boot capabilities to support
the following UEFI network boot functions:

- UEFI PXE with IPv6 support
- UEFI HTTP with IPv4 and IPv6 support
- UEFI HTTP with DNS resolution

Although GRUB already supports TFTP, HTTP, and DNS, it previously lacked
the integration to configure its network stack based on the UEFI device
path or related boot protocols when booting in these network
environments. This series fills that gap by enabling GRUB to
automatically configure the network stack from UEFI device paths or
protocols, so they can work out-of-the-box.

Additionally, for completeness, a new command, net_dhcp6, is introduced
to support IPv6, similar to the existing net_dhcp command for IPv4. This
command auto-configures GRUB's IPv6 interfaces via DHCPv6, enabling
automatic network interface setup and access to remote targets when
booting locally.

The first and last two patches are general fixes to existing network
functionality and can be reviewed or cherry-picked separately from the
patch series.

Thanks,
Michael
