- What I did
Implemented stop mode for fast-reboot. When you send SIGUSR2 to teamd, it will stop in FR mode. That means that:
We have very similar mode: WR, but WR mode activated by SIGUSR1. Also it dumps LACP state to the disk.
- How I did it
Catching USR2 signal.
- How to verify it
Build changed teamd. Install and run it. Capture packets and send teamd USR2 signal. You will see that teamd left all PortChannels untouched, sends LACP packets right before the stop.
