 Apologies - I had committed a mangled patch after test building in the wrong
 tree (sigh).  This should be fully fixed by npf_os.c 1.25, bpf.c 1.258, and
 bpg_filter.c 1.74.
 
 The symptom is that a kernel without MODULAR nor pseudo-device bpfilter,
 but with pseudo-device npf, fails module initialization for built-in module
 npf:
 
 WARNING: module error: Built-in module 'npf' prerequisite 'bpf' failed, error 2
 
 Subsequently, "npfctl reload" will yield a quick panic because the module is
 uninitialized - the usual uvm_fault from a NULL pointer dereference.
 
 I don't think there is an issue with bpf_mtap2; it's a static inline from the
 bpf.h header file and is supplied by bpf_stub.c, not bpf.c.
