Hi

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



commit 37b091c75b13d2f26359be9b77adbc33c55a7581

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

Date:   Mon Jan 13 10:39:31 2020 +0800



    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.



> Fixes: 9efa8d28b ("net/i40e: fix SFP X722 with FW4.16")

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@dpdk.org
