Hi,</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
Finally i have reached a position, where the PHY is detected . Now i am
using kernel version 2.6.14.4 and the gianfar_driver and phy driver seem
to be ok</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
But my problem now is after the PHY is detected (correctly) I don't get
messages like Speed, Full or half duplex, link is up etc. <br>
This means that the driver is not completely up, right ? </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
What might be the problem ? </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
I am loading gianfar driver as a loadable module, but the marvell and generic
phy driver are built into the kernel.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
This is my output :</font><font size=3> </font><font size=2 face="sans-serif"><br>
/ # ifconfig eth0 172.28.8.254 up</font><font size=3> </font><font size=2 face="sans-serif"><br>

</font><font size=2 face="sans-serif"><br>
But after this no output, like Speed, etc.</font><font size=3> </font><font size=2 face="sans-serif"><br>
I checked the code, this info is in a function , gfar_phy_change which
inturn is setup in a PHY change work queue called INIT_WORK. All of this
code is in <br>
drivers/net/gianfar.c</font><font size=3> <br>

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