Perhaps, but I’m not sure that is a guarantee. A good relevant example is when I added get_channels support to enic, which supports all sorts of channels, so I don’t think EOPNOTSUP can be 100% consider reliable in that case. Meaning, if it just so happens that the original author(s) didn't put in get_channels, that doesn’t necessarily mean there is only one queue. And in this case, there is an "other" queue as as well too, as far as I can tell, so the output is at least semi-interesting. Jon
