Well, just in case anybody is wondering...

if you're using the Marvell phy and PCS only option of the TSE it does work if you switch over to 1000BASE-X.

Key is to have Auto-Negotiation Enabled (PCS), and set the FD bit in the dev_ability register (PCS).

On the Marvell Phy enable the same (GBIC mode with AN enabled).
