How to use lacp runner with port priority?

Hi all,

I'm using teamd-v1.31(tag v1.31) from source compile from https://github.com/jpirko/libteam .

This is my network topo:

teamd-1
    |              |
    veth11    veth01
    |              |
    |              |
    veth10    veth00
    |              |
teamd-0

Which is run team-1 with veth11 and veth01, run team-2 with veth10 and veth00.

This is my conf:

### teamd-0

[root@centos8-20240407 public-libteam]# cat ../lacp-t0.conf
{
    "device":       "team0",
    "runner": {
        "name": "lacp",
                "sys_prio": 5,
        "agg_select_policy": "lacp_prio",
        "active": true,
        "tx_hash": ["eth", "ipv4", "ipv6"]
    },
    "link_watch":       {"name": "ethtool"},
    "ports":        {
        "veth00": {"lacp_prio": 30},
        "veth10": {"lacp_prio": 20}
    }
}

### teamd-1

[root@centos8-20240407 public-libteam]# cat ../lacp-t1.conf
{
    "device":       "team0",
    "runner": {
        "name": "lacp",
                "sys_prio": 66,
        "active": true,
        "tx_hash": ["eth", "ipv4", "ipv6"]
    },
    "link_watch":       {"name": "ethtool"},
    "ports":        {
        "veth01": {},
        "veth11": {}
    }
}

Then I run these commands on teamd-0 and teamd-1:

./teamd/teamd -f ../lacp-tX.conf -g -l stdio
ip link set team0 up

In my opinion and code, I think this conf will cause this behavior:

teamd-0 use lacp, use low system priority, use equal port priority.
teamd-1 use lacp, use high system priority, use not euqal port priority.
then veth11 and veth10 will UP, veth01 and veth00 will DOWN.

But in fact, veth11 and veth10 is UP, veth01 and veth00 is also UP.

So: 1) What's wrong with my configure? 2) How to configure use lacp port priority?
