MACsec: Dynamic MACSec ASIC block shutdown to conserve power

Use Media Access Control Security (MACsec) to secure your network with the knowledge that your device is working to optimize power usage. To save power, the device dynamically powers MACsec blocks on and off based on the MACsec configuration. When MACsec is configured on an interface, the device powers on the MACsec block for that port group. If none of the interfaces in a port group are configured for MACsec, the device powers off the MACsec block and traffic bypasses the MACsec block. There might be minimal traffic loss during the power block transition.
