Ok, I think that is the root cause.
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.
