Looks like no le arches may have used the bluetooth code until now -
because I'm now getting

/home/dogcow/work/nbsrc/sys/dev/bluetooth/bcsp.c:1477: warning: 'i' may be used uninitialized in this function

Which does seem to be a very valid complaint; line 1505 is the offending bit:
	if (m->m_len != sizeof(uint32_t) || pkt[i].type == NULL) {

should this be pkt[0].type = NULL ?
