A few process issues:

For a patch set please add a patch 0/X which explains the big picture
of what the patchset does. For a single patch, you don't need one.

Please read:

https://www.kernel.org/doc/html/latest/process/maintainer-netdev.html

It is not clear which tree you intend these patches to be applied
to. This one looks like it should be to net, but needs a Fixes:
tag. The MDIO patch might be for net-next?
