This is the key point really. We don't really care about the Freescale
PCS. We want a generic solution for 1000BASE-KX and 10GBASE-KR,
independent of who makes it, Marvell, Micrel, Broadcom, or Acme.

So, what generic properties are needed for 1000BASE-KX and 10GBASE-KR?
Properties that most/all manufactures are likely to need?
