I'd like to send this patch irrespective of discussion on the other
patches - I already have it committed in my repository with a different
description, but the patch content is the same.

Are you happy if I transfer Andrew's r-b tag, and convert yours to an
acked-by before I send it?

I'd also like to add a patch that allows 2.5G if no other modes are
found, but the bitrate specified by the module allows 2.5G speed - much
like we do for 1G speeds.
