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

    Description: 
In ccw section, 4.3.2.3 Virtqueue Layout lists legacy VQ layout without mentioning it's legacy.

In particular, it mentions "align" variable which only exists
for legacy interfaces.

In MMIO section, 4.3.2.3 Virtqueue Layout lists legacy VQ layout without mentioning it's legacy.

In particular, it mentions "align" variable which only exists
for legacy interfaces.


       Proposal: 
Drop this section completely: VQ layout is documented
in the generic section.
Generalize "2.4.2 Legacy Interfaces: A Note on Virtqueue Layout": replace PAGE_SIZE with "alignment", and document legacy alignment for each transport.
