Re: [Minios-devel] [UNIKRAFT PATCH v3 03/14] plat/virtio: Skeleton for virtio block driver
Hi Felipe,
I am not sure if that line should stay in there. Indeed, `virtio-net`
was a starting point to get familiar with the virtio API, but
virtio-block and virtio-net have different implementations.
It is up to you if that line should stay in there, I sincerely don't know.
The virtio-net authors are:
- Dan Williams
- Martin Lucina
- Ricardo Koller
- Razvan Cojocaru <razvan.cojocaru93@xxxxxxxxx>
- Sharan Santhanam
You found them in `plat/drivers/virtio_net.c`.
Thanks,
Roxana

Were there any authors listed in the original file? If so, please let us know which, we
can fix that on upstreaming.
