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 don't know which pyroute2 version I had used when I tested this
previously, but even on my current system I get this error now.  Thanks
for the fix.

I'd say - hold onto the changes until pmtu.sh works, unless there's
*any* reason for a particular patch to go in early, eg:
 - patch fixes existing bug
 - someone else needs a patch
 - ...
 - a patch which falls under some of the criteria above depends 
   on the patch

I agree. It's better to check field attribute names first. I found this
during manual testing of the "emit_sample" series but I ended up not
needing it for the automated one, so I'm OK waiting for your cleanup
series.

In fact, I also have some patches that try some rework of this part. In
particular, I tried to unify all attributes under a common base class
that would handle printing and parsing. That way, most cases would fall
into "print_str += datum.dpstr(more)" and the "if/elif" block would
shrink significantly.

I'll get stuff out this week for it.

That sounds very good.
