2099b9f27c net: dhcp: Allow "MAY_FAIL" to still try each adapter
This change allows the "MAY_FAIL" DHCP option to still attempt to
contact a DHCP server on each adapter and only give up once each
adapter has failed once.  To get the existing behavior, set the
already-existing ethrotate=no variable.

bc6fc28b86 net: Optionally use pxe client arch from variable
The client architecture that we pass to a dhcp server depends on the target
payload that we want to execute. An EFI binary has a different client arch
than a legacy binary or a u-boot binary.

So let's parameterize the pxe client arch field to allow an override via
the distro script, so that our efi boot path can tell the dhcp server that
it's actually an efi firmware.

20898ea934 distro: Add efi pxe boot code
Now that we can expose network functionality to EFI applications,
the logical next step is to load them via pxe to execute them as
well.

This patch adds the necessary bits to the distro script to automatically
load and execute EFI payloads. It identifies the dhcp client as a uEFI
capable PXE client, hoping the server returns a tftp path to a workable
EFI binary that we can then execute.

To enable boards that don't come with a working device tree preloaded,
this patch also adds support to load a device tree from the /dtb directory
on the remote tftp server.
