Is this a known issue? You need to be careful of 100. It is probably the value of HZ you are using. This means it is probably in jiffies. It could be whoever added support to DSA was using HZ = 1000, and so assumed it has milliseconds, not jiffies, and the API is broken. If you have time, could you dig into this. Trace there where jiffies are used, seconds, and what conversions are preformed, for the default values, netlink API and sysfs API. Once we know where it goes wrong, we can figure out how to fix it.
