Re: [PATCH net-next 1/2] selftests: openvswitch: fix action formatting

Adrian Moreno amorenoz@redhat.com writes:

In the action formatting function ("dpstr"), the iteration is made over the nla_map, so if there are more than one attribute from the same type we only print the first one.

Fix this by iterating over the actual attributes.

I agree, this is an issue. BUT I think it might be better to just filter by field type up front. See:

https://github.com/apconole/linux-next-work/commit/7262107de7170d44b6dbf6c5e...

That version I think ends up being much easier to follow. If you want to take it for your series, feel free. If you disagree, maybe there's something I'm not considering about it.

NOTE that version is just a bunch of independent changes that are squashed together. I have a cleaner version.

I can also bundle up the series I have so far and submit, but I didn't want to do that until I got all the pmtu.sh support working. Maybe it makes sense to send it now though. Simon, Jakub - wdyt?
