[Li, Xiaoyun]

Hi

This issue is already fixed in 20.02 with base code update of the following commit.



commit 37b091c75b13d2f26359be9b77adbc33c55a7581

Author: Xiaolong Ye <xiaolong.ye at intel.com>

    net/i40e/base: extend PHY access AQ command



    Currently FW use MDIO I/F number corresponded with current PF for PHY

    access. This code allow to specify used MDIO I/F number.

But it makes sense to back port this to stable release so it can work with dpdk version <=19.11.

Still some comments inline.

Please be careful about your commit log. If you use mac.type == X722, then that's not just X722 SFP but all X722 devices.

You can just say something like X722 doesn't support adminq operation so disable it.

Please follow the DPDK community code style. Fix line needs commit id of 12 bit.

In this case, should be: Fixes: 9efa8d28b4da ("net/i40e: fix SFP X722 with FW4.16")

And since this fix makes sense for <=19.11, please add this line: Cc: stable at dpdk.org
