Hi all,
I was able to trigger the same issue as reported by Paul, and came
across this patch (+ Daniele's other patch and thread on the libqmi
mailing list). Applying Paul's fix solved the problem for me, changing
the MTU of the QMI interface now works fine. Thanks a lot to everyone
involved!

Thanks a lot to everyone for spotting and fixing my m

Yes, I forgot to add the fixes-tag + comment about stable. Should I submit a v2?

Some devices of the same type all export the same, random MAC address. This
behavior has been seen on the ZTE MF910, MF823 and MF831, and there are
probably more devices out there. Fix this by generating a valid random MAC
address if we read a random MAC from device.

All ZTE MF910 mifis, at least on some revisions, export the same MAC
address (36:4b:50:b7:ef:da). Check for this MAC address and set a random
MAC if detected.
Also, changed the memcpy() to ether_addr_copy(), as pointed out by
checkpatch.

There seems to be a new version of the Microchip Pick16F1454 with a
different PID (0xf2f7). This device should also be ignored by the HID
driver. The PID was observed with the second version of the Yepkit Ykush
USB hub.
