Revision 1.6
10.3.10 END_OF_PACKET Message (GalNet to CPU 16 Block Buffer)
A message from the source GalNet device to the CPU which indicates the end of the packet. This message is used
when the GalNet device forwards one of the following packets directly to the CPU 16 block buffer:
Unicast packets destined for the CPU (Device Number in the address table is equal to the CPU number)
Multicast packets
Unknown packets (if set by bit 6 in the Global Control Register, 0x140028)
BPDU messages
Sniffer packets when the CPU is the target sniffer
EASE packets
The END_OF_PACKET message is written to the first word of the buffer.
Table 20: END_OF_PACKET Message (GalNet to CPU 16 Block Buffer)
10.3.11 END_OF_PACKET Message (GalNet to CPU in Unicast Intervention Mode)
A message from the source GalNet device to the CPU which indicates the end of a unicast packet transfer to the CPU
in intervention mode. The END_OF_PACKET message is written to the first word of the buffer.
