This patchset fixes several bugs that are related to nesting
device infrastructure.
Current nesting infrastructure code doesn't limit the depth level of
devices. nested devices could be handled recursively. at that moment,
it needs huge memory and stack overflow could occur.
Below devices type have same bug.
VLAN, BONDING, TEAM, MACSEC, MACVLAN and VXLAN.

Is this list exhaustive? Looks like qmi_wwan.c perhaps could also have
similar problem? Or virt_wifi? Perhaps worth CCing the authors of those
drivers and mentioning that?

Thank you for working on this!

I couldn't test all interface types.
So there could be more interface types that have a similar problem.
I will send a v4 patch and add more authors to the CC list.

Thank you so much for your review again!
