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

[Prashant Yendigeri]

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.

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).
