Clean up document description and devfs_lookup.
The document description was broken on apropos due to macros,
and make devfs lowercase. The devfs_lookup was changed from
a non existent xref to a function.

Copy, thanks!

That's so exciting! Unfortunately, I have already failed at the very first step, I didn't fix the approved trailed in the commit log.

This is a challenging patch to review, and every time I start to review it, I want to rewrite it to make it clearer. I'll hold off one more time. But I really don't think that enums or switches with fallthroughs really help much.

I agree that it's a bit verbose and I really appreciate your feedback on this patch.
I'd really like to have some flavor of batch insertion in the tree, but I'm not hell-bent on landing the current iteration of the patch.
I'll suspend work on this until your memq removal patch lands as that'll make performance evaluation and development easier.
In the meantime, I'd appreciate if you could share any tips on how you'd like this patch to look like.

This recommendation is useless for users, because they can't control what Linux runtime will be used if they install a Linuxulator application.

Since eventhandlers are called outside the vxlan_sx protection, it is not even guaranteed that the stop event comes after the start, or that events are properly interleaved. In other words, drivers must be prepared for the situation like 'stop without start' or 'two stops after one start'.

Emm, I read the code carefully, both vxlan_start and vxlan_event handlers are called within protection of vxlan_sx. So drivers will get proper event order. Am I missing something important ?
