This patch adds userspace DPDK with rte_flow offload unit
tests. It can be run with the 'make check-rte-offloads'
command; however, it requires a list of VFs that can be
used for offloaded ports. More details on how to set this
up can be found in the testing.rst file.
Also note that currently not all tests are passing. This is
true for both the old rte_flow offload and the new offload
infrastructure.

+Userspace datapath with DPDK and rte_flow offload
+'''''''''''''''''''''''''''''''''''''''''''''''''
+
+To invoke the userspace datapath tests with DPDK and rte_flow offload, the
+same prerequisites apply as above. In addition, six Virtual Function (VF)
+interfaces must be preconfigured and capable of hardware offloading traffic
+between each other.
+
+These six VFs need to be passed as a list of PF PCI addresses with their
+corresponding VF indexes in the OVS_RTE_FLOW_VF_PCI_ADDRS variable.
+For example::
+
+ OVS_RTE_FLOW_VF_PCI_ADDRS="0000:17:00.0,0 0000:17:00.0,1 0000:17:00.0,2

+
+To invoke the rte_flow offloads testsuite with the userspace datapath, run::
+
+ make check-rte-offloads \
+ OVS_RTE_FLOW_VF_PCI_ADDRS="0000:17:00.0,0 0000:17:00.0,1
