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