HEAD should still be creating an enc0. The enc.c file creates an enc_clone= r: IFC_SIMPLE_DECLARE(enc, 1); static int enc_modevent(module_t mod, int type, void *data) { switch (type) { case MOD_LOAD: mtx_init(&enc_mtx, "enc mtx", NULL, MTX_DEF); if_clone_attach(&enc_cloner); break; That '1' is the minimum number of interfaces to create on attach in ifc_simple_attach(). I've no idea why enc0 isn't being created on boot, but it should be. =2D-=20 John Baldwin
