+netdev and Harish who is the current maintainer of bnx2 at qlogic. The patch in question effectively just removes the bnx2_set_power_state() call during "ip link set down". If there is IPMI, the firmware should know the link needs to stay up when the driver resets the device during bnx2_close(). This should be a very common scenario. Please provide the firmware versions to Harish with ethtool -i. Perhaps upgrading the firmware can resolve this issue.
