=== (011) Read Packet ===

Block 011 is the first block with switching between following states.  Its first task is to load the MAC data of the packet.  If filtering inside of the FPGA is required, this block is responsible for it.  The only MAC filtering likely to be needed is a check to see if the destination MAC address matches the MAC address of the CP2200/1, but the CP2200/1 should filter this itself (verify in the data sheet).  If the packet is bad, this block tells the CP2200/1 to skip the packet and returns to block 010.  The MAC filter would be the first substate.

After MAC filtering comes the second substate (or the only substate if MAC filtering is found to be unnecessary).  This reads the first byte of the packet's data and uses it as a switch to determine the transition to the next state:
