Hi all,
This is a followup on the discussion in the DPDK and Virtio monthly meeting.
Michael suggested that layer 2 tests should be created in order to
test the PF/VF behavior in different scenarios without using VMs at
all which should speed up t
Sorry for the delay, I wanted to do a little more performance analysis
before continuing.

How was this tested? I'd suggest building virtio
before and after the changes, stripped binary
should be exactly the same.

Introduce VIRTIO_RING_NO_LEGACY to support disabling legacy
macros and layout definitions.

VRING_AVAIL_ALIGN_SIZE, VRING_USED_ALIGN_SIZE and VRING_DESC_ALIGN_SIZE
are not pre-virtio 1.0, but can also be disabled by VIRTIO_RING_NO_LEGA
Introduce _SPLIT_ and/or _PACKED_ variants for VRING_DESC_F_*,
VRING_AVAIL_F_NO_INTERRUPT and VRING_USED_F_NO_NOTIFY. These
variants are defined as shifts instead of shifted values for
consistency with other _F_ flags.

Switch to using the _SPLIT_ and _PACKED_ variants of vring flags
in split ring and packed ring respectively.
