Please put some reasoning behind this 'wrong'? Different doesn't mean
wrong and 'only one' certainly doesn't mean wrong.
And it also doesn't mean that this hw should not operates correctly
under Linux. I also cannot publish any performance comparison but it
doesn't look wrong at all.

If Intel is the only vendor implements this that way that we may push
the extra queuing into driver
but so far I've seen only athk9 with 11n.
