Set the SFP module connection to support 2.5 Gbps transfer speedfor the
SGMII connection (requires a supporting SFP). By default, transferspeed
of 1.25 Gbps is used, suitable for a more common 1 Gbps SFPmodule.
Note that recent Linux kernels support run-time SFP detection and serdes speed configuration. This patch is still useful for older kernels.

Older kernels I suppose is a nice side effect also, but I was mainly targeting differentiating within U-Boot for network support options.
