| 4 | Subject: [PATCH] net: dsa: Include local addresses in assisted CPU port |
| 5 | learning |
| 6 | |
| 7 | Add local addresses (i.e. the ports' MAC addresses) to the hardware |
| 8 | FDB when assisted CPU port learning is enabled. |
| 9 | |
| 10 | NOTE: The bridge's own MAC address is also "local". If that address is |
| 11 | not shared with any port, the bridge's MAC is not be added by this |
| 12 | functionality - but the following commit takes care of that case. |
