[dpdk-stable] patch 'examples/l2fwd-cat: fix build with PQOS 1.4' has been queued to LTS release 16.11.4

[luca.boccassi@gmail.com]

Hi,

FYI, your patch has been queued to LTS release 16.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/17. So please
shout if anyone has objections.

Thanks.

Kind regards,
Luca Boccassi

Subject: [PATCH] examples/l2fwd-cat: fix build with PQOS 1.4

[ upstream commit 7a08b1d860a3adbc7315bc5ca532d541d07310af ]

Current version is compatible with PQOS version 1.3
but not compatible with higher versions. This change
makes l2fwd-cat example compatible with versions since 1.4
