I=E2=80=99m looking at running FreeBSD on an old Firebox M270.=20
It has a C3558 CPU with integrated X553 LAN controller which connects =
over MDIO to a Marvell 88E6190 switch.
Out of the box the X553 backplane is detected but there doesn=E2=80=99t =
seem to be any attempt at probing the MDIO for connected devices.

I=E2=80=99ve played around with the Intel ixgbe drivers, compiling the =
kernel etc to see if I can figure it out but I=E2=80=99m really =
struggling to understand what needs to be done.

At this stage I=E2=80=99m reaching out to the community to see if anyone =
can clarify something for me=E2=80=A6.are there some fundamental changes =
or additions required to the drivers to make this work, or is it =
something that should work already but needs some options enabling or =
configurations tweaking. I=E2=80=99m reluctant to put more time into =
trawling through the code if it=E2=80=99s a =E2=80=98simple=E2=80=99 =
configuration issue.

Any pointers would be very welcome.
Thank you.=
