BridgeMDB specifying port and group

[Jordi Auge <jordi.auge@xxxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I'm configuring a BridgeMDB using networkd.

I'm trying to produce a networkd configuration with the same effect ad this command:
bridge mdb add dev br0 port socnet0 grp 239.255.42.99 permanent vid 68

This produces the following entry in "bridge mdb show":
dev br0 port socnet0 grp 239.255.42.99 permanent offload vid 68

I have this section in the network config file:
[Match]
Name=br0
(...)
[BridgeMDB]
MulticastGroupAddress=239.255.42.99
VLANId=68

Which produces this entry in "bridge mdb show":
dev br0 port br0 grp 239.255.42.99 temp vid 68

So, I need to set the port (socnet0 vs br0), and the group (temp vs permanent).

As far as I can tell, these options don't seem to be implemented in networkd.

Can anyone please confirm if these feature are supported?
