@GrumpyOldTroll Thanks for the report and PR!
I'll check this when I can.
The same for me, but only using a loop on one of the local interfaces.
(Wanted to see the speed of the hardware).

I would provide more info, if I one let me know.
@mabra, I've merged @GrumpyOldTroll 's PR after some testing, and it works great!
Could you please test on your system?
Thank you both!
