bors 83d8c39f54 Auto merge of #2080 - jbit:freebsd-bpf, r=JohnTitor ... Add FreeBSD BPF structures This PR adds BPF structures that are common between [FreeBSD 11](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/net/bpf.h), [FreeBSD 12](https://github.com/freebsd/freebsd-src/blob/release/12.0.0/sys/net/bpf.h), [FreeBSD mainline/13](https://github.com/freebsd/freebsd-src/blob/main/sys/net/bpf.h) and [DragonFlyBSD 5.9](https://github.com/DragonFlyBSD/DragonFlyBSD/blob/v5.9.0/sys/net/bpf.h). It also fixes the definition of `BPF_ALIGNMENT`, which should be equal to `sizeof(long)`, which is `4` on 32bit FreeBSD. https://www.freebsd.org/cgi/man.cgi?query=arch&sektion=7 > All supported ABIs can be divided into two groups: > * ILP32: `int`, `long`, `void *` types machine representations all have 4-byte size. > * LP64: `int` type machine representation uses 4 bytes, while `long` and `void *` are 8 bytes. I introduced the private `SIZEOF_LONG` const, since I didn't want to introduce a dependency on rust 1.24+ by depending on `libc_const_size_of`. These changes allow my experimental crate to build on FreeBSD: https://github.com/jbit/powerline		2021-02-26 18:22:44 +00:00
