- pfk.h: BSD types/ioctl encoding (OpenBSD bit layout), locks (NET_LOCK=rwsem), pools, timeouts, mbuf shim over sk_buff, ifnet registry, toeplitz/siphash - pfk_mod/pfk_hooks: misc /dev/pf (0600), IPv4 netfilter hook skeleton, DIOCGETSTATUS answered (M1 skeleton; engine ioctls land with pf_ioctl.c) - vendorize/stage-port scripts: deterministic upstream staging with seds (struct renames, IFF_*->PFIFF_*, sa_len drops) logged to docs/porting-notes - fixes: modules_prepare+Module.symvers for out-of-tree builds
