…switch overhead #49 (#54) ### Description of PR Can't cleanly cherry pick the commit from master branch: 34a68d1 disable switchover measuring based on link prober (#49) Summary: Fixes # (issue) Disable part of the feature introduced in #43. The link probing interval will NOT be decreased by default. Link prober state change events will still be posted in `LINK_PROBE_STATS|PORTNAME` in state db. sign-off: Jing Zhang zhangjing@microsoft.com ### Type of change - [x] New feature ### Approach #### What is the motivation for this PR? We need to reconsider the design of this feature. To be more specific, this is a special case of decreasing probing interval, it's for measurement purposes only. We still want to trigger the toggle in 300ms when pack loss happens. The negative count should be 30 instead of 3 when interval is decreased to 10ms.
