pkt_gen: Add support for generating GENEVE frames

Add option to generate GENEVE frames for decapsulation
tests.
IxNet 7.3X does not have a native support of GENEVE protocol. The
template, GeneveIxNetTemplate.xml_ClearText.xml, should be imported
into IxNET for this testcase to work.

Recent changes:
* Updated dependency
* Updated userguide
* Move inner frame variables & srcport/dstport to L4
