Implement mdo_insert_tx_tag to insert the TLV header in the ethernet

If extscs parameter is set to 1, then the TLV header will contain the
TX SC that will be used to encrypt the frame, otherwise the TX SC will
be selected using the MAC source address.

In which case would a user choose not to use the SCI? Using the MAC
address is probably fine in basic setups, but having to fiddle with a
module parameter (so unloading and reloading the module, which means
losing network connectivity) to make things work when the setup
evolves is really not convenient.

Is there a drawback to always using the SCI?
