virtio: add support for tx-queue-size
Type: improvement
DBGvpp# set loggin class virtio level debug
DBGvpp# create int virtio 0000:00:03.0 tx-queue-size 1024
show virtio pci
```
Virtqueue (TX) 1
qsz 1024, last_used_idx 0, desc_next 0, desc_in_use 0
avail.flags 0x1 avail.idx 0 used.flags 0x0 used.idx 0
```
show logging
