    [BNX2X]: Correct Link management · f1410647
    Eliezer Tamir authored
    Properly protect PHY access between two devices on the same board with
    a HW lock.
    
    Use GPIO to clear all previous configurations before changing link
    parameters.
    
    Shut down the external PHY in case of fan failure.
    
    Reducing the MDC/MDIO clock to 2.5MHz due to problems with some
    devices.
    
    Resolve the flow control response according to autoneg with external
    PHY.
    
    Unmasking all PHY interrupts in single write to prevent a race in the
    interrupts order.
    
    LASI indication fixes to work with peculiarities of PHYs.
    
    Disable MAC RX to avoid a HW bug when closing the MAC under traffic.
    
    Disable parallel detection on HiGig due to HW limitation.
    
    Updating the shared memory structure to work with the current
    bootcode.
