Question: How to bind to netlink on Linux?

[al8n]

Hi, when using rustix on linux, I found that it seems that there is no socketaddr_nl, and cannot bind to netlink.

    let mut sa: sockaddr_nl = mem::zeroed();
    sa.nl_family = AF_NETLINK as u16;

    if bind(
      sock,
      &sa as *const sockaddr_nl as *const _,
      mem::size_of::<sockaddr_nl>() as socklen_t,
    ) < 0
    {
      return Err(io::Error::last_os_error());
    }

The above libc code cannot use rustix to achieve.
