i210 KX image with mdio enabled

[Sean_Li]

Hi,

Now I am using I210 KX image (DEVID: 1537).

We want to use this MDIO do some configure since I210 is connect to a switch can be configured by MDIO. And seems it is disabled by default.

I've change the flash context as below based on Dev_Start_I210_Sgmii_NOMNG_8Mb_A2.hex v3.30, but  MDIO still does not work, and ethtool cannot recognize right PHYADD.

flash	word 0x13	word 0x24
Intel KX	0x45: PHYAD: 2	0x0290
My KX	0x43: PHYAD:1	0x4294, MDIO enable, external

Hi Carlos,

Double confirmed  MDIO works. But igb driver will not drive MDIO in KX mode. Thanks.

Hi Carlos,

It is a design using the cited Intel Ethernet Controller.

A typo here,  in fact I am using  Dev_Start_I210_SerdesKX_NOMNG_8Mb_A2.hex v3.30. I download it from i210's spec's link. https://cdrdv2.intel.com/v1/dl/getContent/513655

and modified according to design as I list above.

I found reg 0x0020 works well by mmap.

But I cannot obtain right PHYAD through ethtool.
