https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271101 --- Comment #3 from Alexander V. Chernikov <melifaro@FreeBSD.org> --- (In reply to Navdeep Parhar from comment #2) Ack. The reason is that t4_tracer is using older 13.x cloner KPI. The new K= PI requires the creation function to provide pointer to the created ifnet and = 13.x wrapper tries to guess it by using the requested interface name. As t4_tracer uses different name ('if_initname(ifp, name, ifd->unit);') and does not update the provided name pointer, the search fails, resulting in t= he panic later on. I've created https://reviews.freebsd.org/D39865 to switch t4_tracer to the = new KPI. Afer the conversion, I'm going to delete if_clone_advanced() functions in H= EAD, as t4_tracer is the only remaining customer. --=20 You are receiving this mail because: You are the assignee for the bug.=
