How to config Arria 10 10GBase-R support SFP+ optic module

Hi,everyone!

I'm using the "Arria 10 1G/10GbE and 10GBASE-KR PHY" for a design I'm working on with the Arria 10,and fpga serdes connect to SFP+ optic module.

Described in the manual support edc,on page 6 "Electronic Dispersion Compensation (EDC) support for XFP, SFP+, QSFP, and CFP optical

module",but intel did not explain how to use this function？？？
