## Main features

Several (but not all) of these _main features_ translate to an eBPF program type.
The list of such program types supported in your kernel can be found in file
[`include/uapi/linux/bpf.h`](https://github.com/torvalds/linux/blob/master/include/uapi/linux/bpf.h):

    git grep -W 'bpf_prog_type {' include/uapi/linux/bpf.h
