[U-Boot] phylib + mii + <phy>_parse_status

[Michal Simek <monstr@monstr.eu>]

Hi,

I have done some experiments with phylib and Xilinx ethernet drivers
and I found that mii code show different values for speed and duplex.
I think that the main problem is that there are called miiphy_speed
and miiphy_duplex functions instead of phy parsing functions.

I think that it will be the best to extend
struct phy_driver for
int (*parse_status)(struct phy_device *phydev);

and then reread phydev->speed or phydev->duplex instead of using generic
code which does wrong things.

Then will be good to synchronize FULL/HALF and DUPLEX_FULL/DUPLEX_HALF.

miiphy.h
#define HALF                    22
#define FULL                    44

include/linux/ethtool.h
#define DUPLEX_HALF             0x00
#define DUPLEX_FULL             0x01


And of course speeds:
miiphy.h
#define _1000BASET              1000
#define _100BASET               100
#define _10BASET                10

include/linux/ethtool.h
#define SPEED_10                10
#define SPEED_100               100
#define SPEED_1000              1000
#define SPEED_2500              2500
#define SPEED_10000             10000


Have someone looked at it? Any comments?

Thanks,
Michal
