Notes:
1. The RS0/RS1 PU/PD resistors are not populated. There are pull-down resistors built into the SFP/zSFP modules that select
the lower bandwidth mode of the module.
2. Also available via I2C control. For this and additional information about the enhanced SFP+ module, see the SFF-8431
specification at the SFF-8431 specification website
