As part of this, we import bpf_filter.c from NetBSD. Even though that file is part of the NetBSD kernel, it is also used by userland (as is clear here). Our LWIP service has its own bpf_filter.c implementation but that implementation has certain limits (e.g. on program size) that are fine for a system service but should not apply to userland. The libpcap code has a number of blocks guarded by __NetBSD__, but none of those blocks apply to MINIX 3. In particular, some of the alignment logic used for NetBSD may in fact not work in our case.
