[PATCH] mbuf: fix debug checks for headroom and tailroom
From: Vasily Philipov <hidden>

library code, the rest · Maintainers:
Andrew Morton, Linus Torvalds
rte_pktmbuf_headroom() and rte_pktmbuf_tailroom() should be usable
with any segment, not only with headered ones, so is_header should be 0
when we call for sanity check inside them.
Fixes: af75078fece3 ("first public release")
