Rare project developers

[Alexander Gall <>]

I'm with Gawen here. You either need the SDE + BSP or the SDE + ONLP.
The latter provides platform-dependent support for the QSFP stuff via
the optoe module (AFAIU).  As Gawen says, there is just no way to get
at the I2C QSFP clients without board-specific information, i.e. the
SDE alone is not enough. The "port_map" file only deals with the
serdes-specific stuff.
