Description of problem: create balance-slb port or balance-tcp port with lacp as active and bond-downdelay=60000 bond-updelay=60000. When try down active member, find may_enable status (ovs-appctl bond/show)changed before lisk_state changed(ovs-vsctl get interface) This issue occurred when ovs side configure lacp as active.

After check with Mike. Mike thinks this phenomenon is expected. The bond log message happens during the bridge update, so it could be delayed if something else on the bridge is taking too long. So neither are instantaneous. The DPDK log message is just on a 5 second timer. the bond log message starts off in the main run() function. run() keeps everything up to date and that means calling bond_run(). bond_run() updates which ports are active / inactive, up or down, and decides if flows need to be revalidated. These run in different threads, and because of that 5 second timer. You're a lot more likely to get the bond log message first. If you ran this test 100 times, I bet 75% of the time, the bond log message would come first. Because run() takes less than 5 seconds usually. may_enable is not the same as link status，It also includes things like lacp status. If corresponding switch port down, the lacp status will change. Then appctl check the bond change and display it. lacp status changed earlier than link flapping. That's why may_enable: false. ovs-vsctl get interface ens1f0np0 link_state is complex. OVS is setting that value in OVS DB. So there could be a delay there.
