[PATCH v1 0/7] s390x: Add support for virtio-net-pci boot device

[Zhuoying Cai <zycai@linux.ibm.com>]

This series enables network booting via virtio-net-pci on s390x.

Refactor virtio-net to separate virtio-ccw specific logic and
create generic virtio-net helpers, and add support for booting
from virtio-net-pci devices with proper endianness handling.
Add support for the loadparm property during network boot.

Add corresponding test coverage to verify correct network boot
functionality with virtio-net-pci devices.

Zhuoying Cai (7):
  pc-bios/s390-ccw: Split virtio-ccw and generic virtio net
  pc-bios/s390-ccw: Add dynamic net header size handling
  pc-bios/s390-ccw: Introduce virtio_tswap helpers
  pc-bios/s390-ccw: Add support for virtio-net-pci IPL
  hw/virtio: Add "loadparm" property to virtio net PCI devices booting
    on s390x
  tests/qtest: Add s390x virtio net PCI test to pxe-test.c
  tests/functional/s390x: Add tests for virtio net PCI in
    test_pxelinux.py
