- What I did

On my Windows laptop, I have some networks with type "mirrored" ...

  • "FSE Switch (Loopback Pseudo-Interface 1)"
  • "FSE Switch (Mobile)"
  • "FSE Switch (WiFi)"
  • "FSE Switch (Ethernet 4)"

On startup, Docker tries to adopt all of the networks it learns about from HNS. But "mirrored" isn't a supported network type, so it tries to load a network plugin called "mirrored". That doesn't exist, so it tries again after 1, 2, 4 and 8 seconds - per network (so, a minute's startup delay in total).

- How I did it

Don't try to load plugin "mirrored".

- How to verify it

Dockerd starts up quickly when the host has "mirrored" networks.

- Human readable description for the release notes

- Windows: Improve daemon startup time in cases where the host has networks of type `"Mirrored"`.
