| 4 | Subject: [PATCH] net: dsa: Include bridge addresses in assisted CPU port |
| 5 | learning |
| 6 | |
| 7 | Now that notifications are sent out for addresses added to the bridge |
| 8 | itself, extend DSA to include those addresses in the hardware FDB when |
| 9 | assisted CPU port learning is enabled. |
