One possible implementation:

- at RX: dispatched to the host processor
- at TX: generated by the MAC

> 2. Is CRC processed after all of frame received by the MAC?

Yes, checked on RX. And generated at TX.

A good reference are also Motorola's PowerQUICC MPC8xx and MPC8260 processor
manuals.

See http://199.104.132.208/collateral/M954862812288collateral.htm for a
MPC860 manual.
