[virtio_net] ioctl: unknown message 22e1

[haikupr]

Since I updated to hrev58436, from time to time a flurry of messages related to virtio_net are logged in /var/log/syslog:

2024-12-20 07:25:19 KERN: virtio_net: ioctl: unknown message 22e1
Last message repeated 137 times

There is no other obvious symptoms. This haiku instance run under Bhyve on a FreeBSD host.

At boot time, I also observe a single 2716 unknown message. This is not new, the message is present since at least hrev57257. The message and its surroundings as produced by hrev58436:

2716 == 10006 == ETHER_SET_LINK_STATE_SEM. It appears the virtio driver doesn't support that, but it doesn't need to.

22e1 == 8929 == SIOCGIFSTATS. That was added recently, I guess it might be nice to add that to the driver to reduce spamming. But it's harmless anyway.

Fixed in hrev58441.
