There is no comment for this constraint neither in the code nor in the
commit: http://dpdk.org/commit/66c594904
So, I guess it can be removed.
If a check is needed, it could be added in the relevant drivers.

Helin, Konstantin, please check for Intel drivers.

Ferruh, please take care of this series.
