MACSec operates transparently to IP and above levels. Assign IP
addresses to all connected interfaces, setup routing tables that reflect
your network topology on all connected hosts, use any network
application to exchange data. MACSec will automatically protect
any traffic that flows between hosts that have a security
association over the controlled interface (fm-mac1 in your case).
cat /sys/kernel/debug/fsl_macsec_dpa/<interface> to check the operation.
