[RFC,0/6] Add the netdev support for Intel PAC N3000 FPGA

This patchset adds the driver for FPGA DFL (Device Feature List)
Ether Group private feature. It also adds the driver for the retimer
chips on the Intel MAX 10 BMC (Board Management Controller). These
devices are the networking components on Intel PAC N3000.

Patch #1 provides the document which gives a overview of the hardware
and basic driver design.

Patch #2 & #3 export some APIs to fetch necessary networking
information in DFL framework. These information will be used in the 
retimer driver and Ether Group driver.

Patch #4 implements the retimer driver.

Patch #5 implements the Ether Group driver for 25G.

Patch #6 adds 10G support for the Ether Group driver.
