Thank you Manjahe for addressing both the networking description as well as the typo.

The added information does not look RISC-V specific. We already have doc/board/emulation/blkdev.rst. I would suggest to add a similar file for networking.

There are different noteworthy network devices in emulation (e1000, virtio-net-pci, ...). You can have user network or use tap/tan. You may want to set the mac address. Tftp and DHCP provided by QEMU are of interest. So quite a bunch of information that we can add over time.

Best regards
