to ensure all long options will work well.

Please, be more explicit about the thing you want to fix.

I understand --no-mac-updating is broken.
You want to fix this long option.
Is this correct?


The Fixes: should follow the common format.
I recommend setting this alias in your config so that you only need to
call "git fixline $sha1":
$ git config alias.fixline "log -1 --abbrev=12 --format='Fixes: %h
(\"%s\")%nCc: %ae'"

So here, it should be:
Fixes: fa19eb20d212 ("examples/l2fwd: add forwarding port mapping option")


And I recommend aligning this example with others.
Iow do something like:

                        if (ret) {


In a followup patch, the "mac-updating" option can be removed since
the associated mac_updating variable is set to 1 by default.
