+Physical NICs and Drivers
+-------------------------
+
+SUT and TG servers are equipped with a number of different NIC models.
+
+VPP is performance tested on SUTs with the following NICs and drivers:
+
+#. 2p10GE: x520, x550, x553 Intel (codename Niantic)
+   - DPDK Poll Mode Driver (PMD).
+#. 4p10GE: x710-DA4 Intel (codename Fortville, FVL)
+   - DPDK PMD.
+   - AVF in PMD mode.
+   - AF_XDP in PMD mode.
+#. 2p25GE: xxv710-DA2 Intel (codename Fortville, FVL)
+   - DPDK PMD.
+   - AVF in PMD mode.
+   - AF_XDP in PMD mode.
+#. 2p100GE: cx556a-edat Mellanox ConnectX5
+   - RDMA_core in PMD mode.
+#. 2p100GE: E810-2CQDA2 Intel (codename Columbiaville, CVL)
+   - DPDK PMD.
+   - AVF in PMD mode.
+
+DPDK applications, testpmd and l3fwd, are performance tested on the same
+SUTs exclusively with DPDK drivers for all NICs.
+
+TRex running on TGs is using DPDK drivers for all NICs.
+
+VPP hoststack tests utilize ab (Apache HTTP server benchmarking tool)
+running on TGs and using Linux drivers for all NICs.
