According to Daniel, the networking folks want to let embedded systems
include BPF without requiring the crypto core.

Last I checked the IPv4 stack depended on the crypto API so this
sounds bogus.

I think there's a bit of a mixup here with what I said. To clarify,
requirement back then from tracing folks was that bpf engine and
therefore bpf syscall can be build w/o networking enabled for small
devices, so dependencies preferably need to be kept on a absolute
minimum, same counts for either making it suddenly a depend on
CRYPTO or a select CRYPTO for just those few lines that can be
pulled in from lib/ code instead.
