I. Compilation
==============

You need libnl3 and libgenl3. On Gentoo: dev-libs/libnl package, slot (3).

gcc -o seg6ctl seg6ctl.c -g -Wall -W -lnl3 -lnl-genl-3 -I/usr/include/libnl3

Arguments might change w.r.t. Linux distribution.

II. Usage
=========

1. Add segments 2000:1::10, 2000:1::32 and 2000:1::43 for destination prefix 2000:2::1/128:
   ./seg6ctl --prefix 2000:2::1/128 --add 2000:1::10,2000:1::32,2000:1::43

2. Same, but with cleanup flag set:
   ./seg6ctl --prefix 2000:2::1/128 --add 2000:1::10,2000:1::32,2000:1::43 --cleanup

3. Same, but with HMAC key ID set to 42:
   ./seg6ctl --prefix 2000:2::1/128 --add 2000:1::10,2000:1::32,2000:1::43 --cleanup --hmackeyid 42

4. Display segments table:
   ./seg6ctl --show

5. Flush segments table:
   ./seg6ctl --flush

6. Delete entry for destination prefix 2000:2::1/128:
   ./seg6ctl --prefix 2000:2::1/128 --delete

7. Set a secret for HMAC key ID 42:
   ./seg6ctl --set-hmac 1 --hmackeyid 42
   # Command will prompt for secret, just type it
   # The parameter `1' for --set-hmac is the ID of the hashing algorithm, unused for now, let it at 1

8. Remove the secret for HMAC key ID 42:
   ./seg6ctl --set-hmac 1 --hmackeyid 42
   # Just press enter when prompt is displayed

9. Display HMAC table:
   ./seg6ctl --dump-hmac
