Bradcast packets has no target address on the AVC LAN level but I am not sure if it has no "logical" address.
So, it looks like a broadcast for AVC LAN still have target address (or class) inside the data:
| Data[0] | Data[1] | Data [2] | Data[3] ... |
| ------- | ------- | -------- | ------------|
| Src addr | Target addr (or class) | Command | Data |
| example: ||||
| E4 | 31 | B6 | XX XX XX |
## ECM (0x1C6[0xE4]) -> Broadcast
| Class (Target) | Command | Data | Value |
