Re: Gianfar eth driver on 8540 ppc - for 2.4 and 2.6 : different outputs

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
[   34.041809] 0:00 not found
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 with 
Marvell phy enabled.

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).
