[PATCH v2 0/7] s390x: Add support for virtio-net-pci boot device

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

changlog v1->v2

pc-bios/s390-ccw: Move CCW net setup to virtio-ccw
- Removed the virtio_net_setup() dispatcher; netmain.c now calls
  virtio_ccw_net_setup() directly
- Improved the error message to be CCW-specific

pc-bios/s390-ccw: Add dynamic net header size handling
- Defined VirtioNetHdrMrgRxbuf, which includes VirtioNetHdr and a
  num_buffers field
- Defined header size constants using the sizeof() each struct

pc-bios/s390-ccw: Introduce virtio_tswap helpers
- Edited the commit message to mention that only 16-bit helper function
  is used in this commit

pc-bios/s390-ccw: Add support for virtio-net-pci IPL
- Updated the commit message to change "adds" to "extends" when
  describing endianness handling
- Removed net specific setup/find for PCI device
- Checked for virtio initialization failures during network device
  initialization

hw/virtio: Add "loadparm" property to virtio net PCI devices booting on s390x
- Edited the commit message to avoid implying that PCI netboot will fail
  if a valid loadparm is not provided.

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
- Tested-by: Joshua Daley <jdaley@linux.ibm.com>

----------------------------------------------------------------------

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

Refactor virtio-net to separate virtio-ccw specific logic 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.
