[ovs-dev] [PATCH v3 3/6] system-dpdk: Allow running the dpdk tests from a VM

From: Aaron Conole <aconole at redhat.com>

Some VM configurations result in CPU flags that cause warnings to be issued by
the DPDK libraries.  When these warnings are issued, the tests will fail.

This commit adds the unreliable tsc warning to the list of ignored warnings.
