The attached tcpdump traces are from armv7 and amd64 systems. The problem
on the armv7 system is very reproducible even though the pypi.io site uses
different hosts at random.
It has been many years since I analysed tcp traces and then it was with
wireshark and so my abilities are lacking. However I am suspicious about
the sequence of packets:

I can reproduce this on my Allwinner A20 system (Banana Pi) but on on NXP
i.MX6 (Cubox-i4). That suggests this is a network driver bug.
However, my device is using dwge(4), whereas yours is using dwxe(4) isn't
it? It isn't inconceivable that both drivers have the same bug though,
since the hardware is very similar.
