So, you are saying that it is likely that if I change rndis.c and replace
"dev_get_stats(net, &temp)" with plain "&net->stats" things should work
correctly (rndis.c does not use the "temp" so it's not a problem)?

I actually did that and nothing seems to crash but dunno if it didn't
make g_ether report some not fully up-to-date values or something.
