Well, I see no reference of the "flow" neither in the include/linux/mii.h
nor in the drivers/net/phy/*. :-/ Thus today there is no such register
bit we can emulate?..

..and I looked into few drivers (gianfar, ucc), and they seem to use
hard-coded flow control values, thus they don't speak to the PHYs
about that.
Can you give any reference to the driver that needs that parameter?
Does it use PHY subsystem to obtain flow-control on/off information?
Thanks,
