Thanks for the comment! This is fine, but much better since it's commented! 5:D

Will this exist on all kernels, or should this be an optional set_type (as a few lines below)?

I think it will exist - but it never hurts to double check! I'll look into it.

I confirm net_device exists at least from 2.6.30, so it should be safe.

Liiiiiittle bit ugly, but it's only a line, so I guess that'll be ok. 5:S Can't think of how to improve it, so....

Hello!
This PR brings very basic versions
ip.Linkandip.Addrplugins for linux which I hope to complete with the full suite of ip information, e.g.ip route show,ip neigh show, etc etc.They don't have smear protection yet, I can add that if it looks like this is the correct way of doing things. They are based on the vol2 plugin
ifconfigbut I've tried to include a little bit more information. I don't have a good selection of samples with very old kernels in them so I haven't done the path that using thedev_basesymbol rather thannet_namespace_listyet.I've tested on kernels from v3 to v6 but I'd always welcome more testing! No doubt I've missed something somewhere.
Here is some example output from two different samples.
