There are still unresolved comments on the first patch of the series.
However, I preferred to postpone this subject so that we can get the
headers cleanup and the new bitops API in rc1.
I skipped this first patch and dropped the check added by 1ee492bdc4ff
("buildtools/chkincs: check missing C++ guards").
Thanks for the big cleanup on DPDK headers, let's finish the work on
the headers check in rc2.
Series applied.
