Detailed Description

If we operate in user space we only need to include bpf.h and define the userspace API macros. For kernel programs we need to specify a list of kernel helpers. These are taken from here: https://github.com/torvalds/linux/blob/master/tools/lib/bpf/bpf_helpers.h A helper structure used by an eBPF C program to describe map attributes for the elf_bpf loader FIXME: We only need this because we are loading with iproute2
