[Qemu-devel] [PULL 02/29] tests: Test IPv6 and ppc64 in the PXE tester

[David Gibson <david@gibson.dropbear.id.au>]

From: Thomas Huth <thuth@redhat.com>

The firmware of the pseries machine, SLOF, is able to load files via
IPv6 networking, too. So to test both, network bootloading on ppc64
and IPv6 (via Slirp) , let's add some PXE tests for this environment,
too. Since we can not use the normal x86 boot sector for network boot
loading, we use a simple Forth script on ppc64 instead.
