Please reindent the comment properly, taking care of the space before
the parenthesis.

Another comment that concerns the whole patchset. It's maybe a question
for Thomas, but I think that having patches that don't break compilation
between each other would help when bissecting.

In this case, I wonder if it's possible to split in something like:

- change PKT_TX_IPV4 and PKT_TX_IPV6 definition
- add + rename flags (update them in mbuf + testpmd + i40)
- rename inner_l{23}, l{23} in l{23}, outer_l{23} (update them in mbuf
  + testpmd + i40)

I'm not sure it's feasible, I let Thomas give his mind about this.
