SubjectUnsupported phy-connection-type sgmii-2500 in arch/powerpc/boot/dts/fsl/t1023rdb.dts
Hello!

In commit 84e0f1c13806 ("powerpc/mpc85xx: Add MDIO bus muxing support to
the board device tree(s)") was added following DT property into DT node:
arch/powerpc/boot/dts/fsl/t1023rdb.dts fm1mac3: ethernet@e4000

phy-connection-type = "sgmii-2500";

But currently kernel does not recognize this "sgmii-2500" phy mode. See
file include/linux/phy.h. In my opinion it should be "2500base-x" as
this is mode which operates at 2.5 Gbps.

I do not think that sgmii-2500 mode exist at all (correct me if I'm
wrong).

Could you look at this DT property issue? What should be filled here?

I'm CCing netdev and other developers as I see that there is lot of
times confusion between sgmii, 1000base-x and 2500base-x modes.
