Description of Problem DHCP network fails to come up with TG3 driver (bcm 5703X) connected to network through a 3com gigabit switch (connection to system is 1000Mbps, full duplex) When configured for DHCP, attempting to bring up the network (either on boot or with ifup) fails with "...no link present? Check Cable?" Disabling the following lines in ifup: ip link set ${DEVICE} down exit 1 below the error print results in the network coming up correctly at 1000Mbps, full duplex with a DHCP suplied address. This does not happen when configured for a static IP address. Version-Release number of selected component (if applicable): 2.4.18-7.80 How Reproducible: always when connected to the gigabit switch. I have not been able to repro when connected through a 100Mbps switch. Steps to Reproduce: 1. configure tigon 3 network for dhcp 2. ifup <tigon 3 device> 3. see error 4. ifdown <tigon 3 device> 5. comment out 2 lines of ifup 6. ifup <tigon 3 device> 7. see success Actual Results: network doesn't come up correctly when connected to gigabit switch Expected Results: network to come up without error connected to either switch Additional Information: lspci -vv of device will be attached

Please change the sleep in check_link_down in network-functions from 2 seconds to 5 seconds; MII negotiation can take up to 5 seconds and in this case it is taking longer than two.
Changed in 6.90-1.
