    ixgbe: Compare flow control against requested mode
    
    The flow-control sysctl represents the configured policy, while
    current_mode is the mode negotiated with the link partner.  Comparing a
    new request with current_mode can needlessly reprogram an unchanged
    policy or skip a requested policy change that happens to match the
    current negotiation result.
    
    Compare with requested_mode before deciding that no update is needed.
