Hi,

Downloaded 2.6.16.26 and booted up and got this :

/ # ifconfig eth0 172.28.8.254 up
[   34.034596] 0:00 not found
[   34.037330] eth0: Could not attach to PHY

SIOCSIFFLAGS: No[   34.044526] eth0: Could not attach to PHY
 such device
SIOCSIFFLAGS: No such device

I had enabled all the PHY devices in .config and also tried only =20
with Marvell phy enabled.

Are you doing this on a custom board?  If so what is the PHY address =20
for the Marvell phy you are using?

Hi,

The gianfar driver of 2.6.12 and 2.4.20 give different outputs on
the same PPC 8540 board.

What could be the reason ?

Output on 2.4.20 :
/root # ifconfig eth0 172.28.8.254 up
eth0: PHY is Marvell 88E1011S (1410c62)
eth0: Auto-negotiation done
eth0: Half Duplex
eth0: Speed 10BT
eth0: Link is up

Output on 2.6.12
/ # ifconfig eth0 172.28.8.254 up
 eth0: PHY is Generic MII (ffffffff)

It looks like your 2.6.12 kernel isn't handling the PHY correctly.
I'd recommend upgrading to something newer which has the phylib
(can't remember which 2.6 that went into).
