As I said earlier, when we call bnx2_shutdown_chip(), we inform the
firmware that the driver is shutting down.  The firmware should know
that there is IPMI firmware and the link needs to stay up.

In the older driver, we would also call bnx2_set_power_state() which
would send some additional messages to the firmware before putting the
device in D3hot.  May be these messages are required by the firmware to
keep the link up.  Harish, please check with your firmware team.
Thanks.
