In Ethernet networks, the MAC layer is the first layer to detect the destination address of the received message.

my questions: is that means that the transceiver shall take a copy of each message on the bus and forward it to the MAC layer who will decide to accept that message or discard it? If so, this means that the MAC layer must have a very large buffers to save all that intended and non intended message. am I correct ?

You need to filter the incoming data in real time, possibly use a small elastic buffer to synchronize the MAC module.
