Wrong headline format:
        app/testpmd: use rte_ether_unformat_addr

Does not like the "_" in the commit message.
This also affects four of the other patches in the set.


/devtools/checkpatches.sh  v4-8-8-app-testpmd-use-rte_ether_unformat_addr.patch

WARNING:LONG_LINE: line over 80 characters
#125: FILE: app/test-pmd/parameters.c:737:

total: 0 errors, 1 warnings, 88 lines checked

Long line should probably be fixed.

Bernard
