Configuring Broadcom NetXtreme BCM5721 in full duplex mode

[Laudou, Christophe]

Hi,

We are using Broadcom  NetXtreme BCM5721 NIC on our sun fire x2100 with
RH4 UPDATE3.
We have a lot of connectivity issues with these and we cannot configure
them in full duplex mode.
Driver in tg3 fully supported.

"ethtool -s eth1 duplex full" giev a return code 0.
"mii-tool -F 100baseTx-FD eth1" is ok as well.

but

Anyone faced problems configuring the tg3 driver to full duplex?
