  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

Does this check work right? The version number in git right now seems to
be just 10100, which would use the "old" path here, despite being latest
code? https://github.com/01org/intel-cmt-cat/blob/master/lib/pqos.h

I will try and follow up with the maintainers of the pqos files, and see
how the version numbers in pqos.h are meant to work.

Regards,
/Bruce

Sorry, added redundant zeros. The correct version number should be 103. 
But there is one pitfall in this commit 
6a6d9ef0cae67efe63a394f09fa587b6fc8b1046 but for other case 103 will work.
