Summary
Using limiters for network testing - it appears that modifying config of limiters so that they are inactive does not appear to remove them from active limiters (Diagnostics / Limiter Info).

Expected behaviour
Limiters set inactive should be inactive

Actual behaviour
Limiters set inactive are active

Steps to reproduce:

1. Firewall / Traffic Shaper / Limiters - click New Limiter (eg. I created one "Down25M" for downloads and another "Up5M" for uploads)
2. Save limiter(s)
3. Apply changes
4. Diagnostics / Limiter Info - verify limiter config
5. Firewall / Traffic Shaper / Limiters - select Limiter & uncheck Enable box
6. Save limiter
7. Apply changes
8. Diagnostics / Limiter Info - observe limiter marked inactive is still showing as active

Workaround 1: Disable applicable firewall rules (using in/out pipe) to disable use of one or more limiter(s)
Workaround 2: Reboot if all limiters are no longer required. Given the processing overhead of dummynet limiters this seems to be only way of fully disabling limiters
