| 6 | While the hardware is capable of performing learning on the CPU port, |
| 7 | it requires alot of additions to the bridge's forwarding path in order |
| 8 | to handle multi-destination traffic correctly. |
| 9 | |
| 10 | Until that is in place, opt for the next best thing and let DSA sync |
| 11 | the relevant addresses down to the hardware FDB. |
