ok, so my draft for v6, I'll use:
- PLLS needs a 161.1328125 MHz reference clock, for which 2x40g,
40g4x10g and 100g4x10g program it. It can come from the SD1
PLLS reference clock input, or from the PLLF one with
SRDS_INTRA_REF_CLK_S1=1. A 156.25 MHz PLLS reference clock is
not supported. With protocol 13 PLLS is not in use, so nothing
checks that clock before these modes start it.
Thanks,
Vincent
