Broadcom NIC is BCM57760, phy is BCM57780. The problem I'm seeing is that the downing and interface leads to permanent link loss, even after interface is upped again. E.g, to reproduce the problem it is sufficient to run: modprobe tg3 ifconfig eth2 up ifconfig eth2 down ifconfig eth2 up After ifdown PHY LEDs also go down and do not come back after ifup. Ethtool reports that no link is detected. After reloading the driver the link comes back. Am I the only one seeing this problem ? Any help on fixing this is appreciated. Thanks a lot. Felix.
