Agreed.

There are a few controllers where we may -eventually- add TCQ support,
controllers that do 100% of TCQ in hardware. But that's so far down the
priority list, it's below just about everything else.

There may just be little motivation to -ever- support TCQ, even when
libata is the 'main' IDE driver, sometime in the future.

I give an outline of queueing stuff at
