[dpdk-dev] [PATCH 51/63] net/ice/base: update switch training packets with open ports

[Qi Zhang <qi.z.zhang@intel.com>]

This patch updates UDP tunneled training packets with an appropriate
UDP dest port. For the correct profile to be chosen, an open tunnel
port must be included in the training packet.

Added GENEVE tunnel labels in the test package in order to test GENEVE
tunnel rule creation.
