Hi Miroslav,

It seems the changelog cannot be opened because of 403.

BTW, do you have any suggestions what kind of tests we should do specifically for the update?

Beside testing of the other bugs filed for linuxptp, which will be fixed by this rebase, I think it would be nice to test the new fast slewing of the system clock (10% instead of 500ppm) with ptp4l and SW time stamping or phc2sys.

I'm considering to rebase to a post-1.4 git snapshot (2b099cf) to include the new adaptive linreg servo.

BTW, I'll include in the package linuxptp-testsuite with clknetsim and run it in rpm %check to have better testing coverage.
