Three patches discussed and reviewed on the ipxe-devel list. Fixes issues with virtqueue sizes >256. To reproduce, run QEMU with:

-device virtio-net, ..., disable-modern=off,disable-legacy=on,rx_queue_size=1024

for modern virtio and

-device virtio-net, ..., disable-modern=on,disable-legacy=off,rx_queue_size=1024

for legacy virtio.

Thank you,
