[dpdk-dev] [PATCH v3 1/6] mbuf: don't generate invalid mbuf in clone test

[Stephen Hemminger <stephen@networkplumber.org>]

The test for cloning changed mbuf would generate an mbuf
whose length and segments were invalid. This would cause a crash
if test was run with mbuf debugging enabled.

Fixes: f1022aba76a5 ("app/test: rename mbuf variable")
