gnrc_ipv6_ext: merge _handle_rh and gnrc_ipv6_ext_rh_process #10238

miri64 · 2018-10-24T12:42:13Z

Contribution description

It makes much more sense (and saves us a huge ifdef), when _handle_rh and gnrc_ipv6_ext_rh are merged into one function.

Testing procedure

I used scapy again for testing (see testing procedure in #10234).

Issues/PRs references

Depends on ~~#10231~~ (merged) and ~~#10234 (and its dependencies)~~ (merged).

AFAIS the packet is being freed when it's expected. I'm OK with the code design.

... after the merge, I mean :)

The documentation also looks OK.

sys/net/gnrc/network_layer/ipv6/ext/rh/gnrc_ipv6_ext_rh.c

It's a lot cleaner and makes more sense if we merge those two.

miri64 · 2018-12-18T18:04:34Z

Changed @cgundogan mailing addresses as requested by him.

miri64 · 2018-12-18T18:04:44Z

(and squashed directly).

cgundogan

code change looks sensible and comments by @jia200x were already addressed. ACK
