Hi, I am running linuxptp version 2.0 in software timestamp mode, and I found 
the "master offsets" are all over the places. In ~7000 offset measurements, 
more than 50% is greater than 100 micro-sec. Maximum offsets observed is around 
300 micro-secs.  I wonder anyone ran linuxptp in software timestamp mode and 
what accuracy level was observed.
My master clock and PTP clients on are a local network with no PTP-support 
switches. There are 4 switches along the path between the master clock and the 
clients. When I ran linuxptp in hardware timestamp mode in the same network 
setting, I achieved great results: 90% of master offsets is within 1 micro-sec. 
In software timestamp mode the master offsets are higher than expected.  Is 
there anything I can do to improve the accuracy?
