I wondered if I should remove it but decided to not do that for
compatibility reasons. The driver not supporting it any more is a
different thing.

It is (was) inconsitent and did some things in strange ways. For example
instead of disabling RC it only disabled the corresponding irqs and
flushed the fifo before reenabling. I couldn't test it because I don't
have such hardware though.

I expect them to cry at some point if they exist. In this case I'm
willing to help them to reinstanciate support for it.

Best regards
