It seems that it hooks dev_get_tstats64 as ndo_get_stats64=20 but it never allocates tstats, so any ifconfig / ip link run after the device is create immediately crashes the kernel. I don't see any tstats in this driver history or UDP tunnel code so I'm moderately confused as how this worked / when it broke. If I'm not missing anything and indeed this driver was always broken we should just delete it ?
