SFP+ related differences between Everest DEV Board PROTO and

Revision A and B

On Everest DEV Board PROTO the SFP+ signals

RX_LOS

,

RS0

,

RS1

,

TX_DIS

and

TX_FAULT

could only be accessed via the I2C I/O expander PCA9538 that is connected to

the same I2C bus as the SFP+ interface itself.
