[Qemu-devel] [PATCH 2/4] tests/pxe-test: Use table of testcases rather than open-coding

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

Currently pxe-tests open codes the list of tests for each architecture.
This changes it to use tables of test parameters, somewhat similar to
boot-serial-test.

This adds the machine type into the table as well, giving us the ability
to perform tests on multiple machine types for architectures where there's
more than one machine type that matters.

NOTE: This changes the names of the tests in the output, to include the
      machine type and IPv4 vs. IPv6.  I'm not sure if this has the
      potential to break existing tooling.
