Adding ports to an LACP group after the daemon started

[David Shwatrz]

Hello,
I created an LACP group by preparing a config file; I put two entries
for two ports, eth0 and eth1, in that config file (lacp.conf) and I
ran
the teamd daemon successfully with this configuration by:

teamd -f lacp.conf

Now I want to add additional interfaces to this LACP group, like eth2
and eth3, setting values for port members, like lacp_key.

If I try:
teamdctl team0 port add eth2 lacp_key=56
I get an error (Unknown command).

I know, of course, that I can add this entry for eth3 in the lacp.conf file
and restart the daemon.

But the question is:
After the daemon is started, setting an LACP group, how can I add
ports to it such that various port members (like lacp_key or priority)
can be set ? (without restarting the daemon)

regards,
DavidS
