net: filter: rename 'struct sock_filter_int' into 'struct bpf_insn'
eBPF is used by socket filtering, seccomp and soon by tracing and exposed to userspace, therefore 'sock_filter_int' name is not accurate. Rename it to 'bpf_insn' Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S. Miller <davem@davemloft.net>
