Yeah, the AENs are sent from NIC to BMC and the code follows it. The code
is tested on IBM's openPower server where a BMC (ARM system) and host (
Power system and NIC) are included. So the host, the far end and NIC can
be regarded as equivalents.

It's correct. The figure included in the commit log might give the illusion
that NCSI packets are sent over network traffic.
