Sorry, I don't grok that now: | half way between the PMULL based implementation and the PMULL one doesn't mean anything? Will

Yes, one of those PMULLs should say generic (I thought I'd sent a followup saying that, sorry).

The NEON implementation of crctd10dif is registered with a priority of 100 which is identical to that used by the generic C implementation. Raise the priority to 150, half way between the PMULL based implementation and the NEON one, so that it will be preferred over the generic implementation.
