Hello all, I am a programmer,I write a driver for digital21143 =
evaluation
board,its MII chip is ML6692.
I find the ML6692's IEEE id is all 0xFFFF for all MII addr(0-31),so I =
use=20
the GENERIC value to set the MII Control reg,the MII addr is 0, it =
worked.
So if you come across this problem,please modify the driver ,not as =
:
int mii_status =3D mdio_read(dev, phy, 1);
if (mii_status !=3D 0xffff && mii_status !=3D 0x0000) {
in tulip.c.
