-
-    According to 6.4.15 of IEEE 802.1AX-2014, Figure 6-22, the state that the
-    port is selected moves MUX state from DETACHED to ATTACHED.
-
-    But ATTACHED state does not mean that the port can send and receive user
-    frames. COLLECTING_DISTRIBUTION state is the state that the port can send
-    and receive user frames. To move MUX state from ATTACHED to
-    COLLECTING_DISTRIBUTION, the partner state should be sync as well as the
-    port selected.
-
-    In function lacp_port_actor_update(), only INFO_STATE_SYNCHRONIZATION
-    should be set to the actor.state when the port is selected.
-    INFO_STATE_COLLECTING and INFO_STATE_DISTRIBUTING should be set to false
-    with ATTACHED mode and set to true when INFO_STATE_SYNCHRONIZATION of
-    partner.state is set.
-
-    In function lacp_port_should_be_{enabled, disabled}(), we also need to
-    check the INFO_STATE_SYNCHRONIZATION bit of partner.state.

-    libteam: resynchronize ifinfo after lost RTNLGRP_LINK notifications
-    
-    When there's a large number of interfaces (e.g. vlans), teamd loses
-    link notifications as it cannot read them as fast as kernel is
-    broadcasting them. This often prevents teamd starting properly if
-    started concurrently when other links are being set up. It can also
-    fail when it's up and running, especially in the cases where the team
-    device itself has a lot of vlans under it.
-    
-    This can easily be reproduces by simple example (in SMP system) by
-    manually adding team device with a bunch of vlans, putting it up,
-    and starting teamd with --take-over option:
-    
-      root@debian:~# ip link add name team0 type team
-      root@debian:~# for i in `seq 100 150` ; do
-      > ip link add link team0 name team0.$i type vlan id $i ; done
-      root@debian:~# ip link set team0 up
-      root@debian:~# cat teamd.conf
-      {
-        "device": "team0",
-        "runner": {
-          "name": "activebackup"
-         },
-        "ports": {
-          "eth1": {},
-          "eth2": {}
-        }
-      }
-      root@debian:~# teamd -o -N -f teamd.conf
-    
-    At this point, teamd will not give any error messages or other
-    indication that something is wrong. But state will not look healthy:
-    
-      root@debian:~# teamdctl team0 state
-      setup:
-        runner: activebackup
-      ports:
-        eth1
-          link watches:
-            link summary: up
-            instance[link_watch_0]:
-              name: ethtool
-              link: up
-              down count: 0
-      Failed to parse JSON port dump.
-      command call failed (Invalid argument)
-    
-    If checking state dump, it will show that port eth2 is missing info.
-    Running strace to teamd will reveal that there's one recvmsgs() that
-    returned -1 with errno ENOBUFS. What happened in this example was
-    that when teamd started, all vlans got carrier up, and kernel flooded
-    notifications faster than teamd could read them. It then lost events
-    related to port eth2 getting enslaved and up.
-    
-    The socket that joins RTNLGRP_LINK notifications uses default libnl
-    32k buffer size. Netlink messages are large (over 1k), and this buffer
-    gets easily full. Kernel neither knows nor cares were notification
-    broadcasts delivered. This cannot be fixed by simply increasing the
-    buffer size, as there's no size that is guaranteed to work in every
-    use case, and this can require several megabytes of buffer (a way over
-    normal rmem_max limit) if there are hunderds of vlans.
-    
-    Only way to recover from this is to refresh all ifinfo list, as it's
-    invalidated at this point. It cannot easily work around of this by
-    just refreshing team device and its ports, because library side might
-    not have ports linked due to events missed, and it doesn't know about
-    teamd configuration.
-    
-    Checks now return value of nl_recvmsgs_default() for event socket. In
-    case of ENOBUFS (which libnl nicely changes to ENOMEM), refreshes
-    all ifinfo list. get_ifinfo_list() also checks now for removed interfaces
-    in case of missed dellink event. Currently all TEAM_IFINFO_CHANGE
-    handlers processed events one by one, so it had to be changed to support
-    multiple ifinfo changes. For this, ifinfo changed flags are cleared
-    and removed entries destroyed only after all handlers have been called.
-    
-    Also, increased nl_cli.sock_event receive buffers to 96k like all other
-    sockets. Added possibility to change this via environment variable.

-From: Ying Xie <ying.xie@microsoft.com>
-Date: Fri, 26 Apr 2019 23:30:38 +0000
-Subject: [PATCH] teamd: do not process lacpdu before the port ifinfo is set
-
-Now the port ifinfo will be set in obj_input_newlink when a RTM_NEWLINK
-event is received.
-
-But when a port is being added, if a lacpdu gets received on this port
-before the RTM_NEWLINK event, lacpdu_recv will process the packet with
-incorrect port ifinfo.
-
-In Patrick's case, as ifinfo->master_ifindex was 0, it would skip this
-port in teamd_for_each_tdport, which caused lacp_port->agg_lead not to
-be updated in lacp_switch_agg_lead. Later the lacp_port actor would go
-to a unexpected state.
-
-This patch is to avoid it by checking teamd_port_present in lacpdu_recv
-so that it would not process lacpdu before the port ifinfo is set.
