That's some positive news alongside the crash log: it seems that a
part of the driver works! :-)

I need to have a closer look at the pkg_offset and struct
rtw_rx_pkt_stat which we receive.
Recently my own MangoPI MQ-Quad arrived but I did not have the time to
set it up yet. I'll try to do so during the weekend so I can debug
this on my own.

Please ping me next week in case I haven't provided any update until then.
