I have not downloaded your tcpdump file yet to see your details. On my system, I
am unable to duplicate your results. I used dd with /dev/urandom as the source
to create files of 1024, 2048, 4096, 8192, 16384, and 32768 bytes. All of these
could be transmitted to a second host on my local network using scp.

What are the details of your device? Please post the output of 'dmesg | grep -i
rtl'.
