What. +hostap list.

This makes no sense, is that a tshark bug in one of the versions?

Maybe we should just use the JSON output, and parse that, but if tshark
now has a different idea of what the "wlan.mesh.config.cap" field is,
that won't help us at all?

Older versions were misparsing the HE element, but that has a length so
should only affect the HE element *itself*?


So ultimately, what do we do here?

Should we take this and sort out the tests?
