[systemd-devel] [PATCH v3] Add FDB support

Hi Johann,
Also, note that VlanId is optional. It makes more sense for switch ports.
Regarding my “em1” (Ethernet management) interface, probably I should have send an example without VLANId.
And “BridgeFDB”s  are in the .network following the logic of routes.

To be clear look at the outputs below:

1.       for a normal port:
>bridge fdb show dev em1
           44:44:12:34:56:70 self permanent
           44:44:12:34:56:71 self permanent
           33:33:00:00:00:01 self permanent
           01:00:5e:00:00:01 self permanent
           33:33:ff:8f:e7:3f self permanent
           01:00:5e:00:00:fc self permanent
           33:33:00:01:00:03 self permanent

        2. for a switch port:
>bridge fdb show dev sw0p1
14:44:12:34:56:70 vlan 2 self permanent
14:44:12:34:56:71 vlan 10 self permanent

Hi Tom,

I've formatted the patch based on our previous discussions. This one has support only for adding FDB entries.

An example configuration is like below:












Please let me know what you think.



If I start trying to match this with the entire type network files and their path ( feel free to correct me where I'm wrong here )
It would have to look like this...

Ignore my mac address entry confusion with the bridge mac addresses in the MAC learning table and the interface mac address here ( em1 ) which somewhat would have been eliminated if we had [BridgePort] and arguably [BridgePortFDB] sections in the network file
