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 lshw: description: Ethernet interface product: NetXtreme BCM5721 Gigabit Ethernet PCI Express vendor: Broadcom Corporation physical id: 0 bus info: pci@04:00.0 logical name: eth1 version: 11 serial: 00:e0:81:5b:e2:f1 size: 100MB/s capacity: 1GB/s width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd a utonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.10 duplex=half ip=172.16.8. 100 link=yes multicast=yes port=twisted pair speed=100MB/s Anyone faced problems configuring the tg3 driver to full duplex?
