Attached netstat-s.log2.txt after the box was up during the night.

hw.usb.debug: 0 -> 255

# sysctl hw.usb.debug
hw.usb.debug: 255

There is nothing printed to the console and I searched for the DEBUG logs in
/var/logs/system.log.
I also tried with value '1' because I found a website saying value 1 is to
enable debug mode - just to exclude that.

# sysctl hw.usb.debug=1
hw.usb.debug: 255 -> 1
# sysctl hw.usb.debug
hw.usb.debug: 1

Same: Noting on console nor system.log. 
There is nothing logged or I don't know where to find the logs. Do you know
where the logs are?

> Did you verify two such adapters back2back with iperf, for packetloss and
other issues?

On FreeBSD 10.3-RELEASE-p19 is one adapter and on my other box containing
FreeBSD 10.1-RELEASE-p25 is another adapter.

After I did some bandwith test with slow performance, I have those
statistics (full output off netstat -s attached):

# netstat -s | egrep -i 'loss|retran'
                0 data packets (0 bytes) retransmitted
                0 data packets unnecessarily retransmitted
        0 retransmit timeouts
                0 retransmitted
                0 retransmitted DATA chunks
                0 fast retransmitted DATA chunks
                0 TSN's marked for Fast Retran

Is that the information you are asking for?

Thank you for your time, I'm very interested in finding the root cause for
this one.

Have a good day
Tom
