By the way, I just noticed that this bug had already been fixed into
my cmdline project onto my personal website some time ago:
http://git.droids-corp.org/?p=libcmdline.git;a=commitdiff;h=52e1d5772d1f465a013e65b8ae6e43a027438ed6

Hi Olivier,

Great, so then maybe we should plan for an update of the DPDK command line library to your latest code base.

Are the code changes massive, i.e. would this be a big task?

Thanks,
Cristian

There have been some reworks, but it is not a major merge. It will
require some few ones to be done carefully such as:

http://git.droids-corp.org/?p=libcmdline.git;a=commit;h=f32d30f48ddfb55b86efd695e0dd144e9d15401e

In order to ease the merge, it can be started from commit 090c2ba0d6b.
Since cmdline is quite isolated in dpdk, it should be manageable.

Currently, I do not get time to do such merge. But I'll be pleased
review patches that update it.

Regards,
Olivier
