I found this err in "loadbalance" and "lacp" runner when adding ports.
It's caused by trying to set "enabled" option in .port_link_changed()
When a new port is added, the first 'port changed event' process is
earlier than CMD TEAM_CMD_OPTIONS_GET, in this CMD, all
the options are synchronized from kernel.
It means there's no 'enabled' option yet when calling port_link_changed
in the first 'port changed event' process. In lb_event_watch_port_link_changed
and lacp_event_watch_port_changed, they call teamd_port_check_enable
to set 'enabled' option. this err is triggered.
I'm not sure why teamd_port_check_enable needs to check if
'enabled' option exists. I checked the ab's .port_link_changed(),
it just sets it by calling team_set_port_enabled(), instead of
checking 'enabled' option first.
can we just use team_set_port_enabled to set it directly in
.port(_link)_changed OR improve teamd_port_check_enable
to avoid this err ?
