[PATCH linux dev-4.10] fsi: core: Allow more BREAKs to recover a failing link

This seems somewhat suspicious to me. Do we have any indication from the
CFAM documentation, or the folks responsible for the CFAM implentation,
that multiple breaks will actually cause any difference in behaviour
that a single one? Or is this based only on experimentation?

I'm worried that we'd be papering-over the underlying issue here.

Regards,
