+Tunnels support
+---------------
+
+NVGRE, VXLAN and GENEVE tunnels are supported on SFN8xxx family adapters
+with full-feature firmware variant running.
+**sfboot** should be used to configure NIC to run full-feature firmware variant.
+See Solarflare Server Adapter User's Guide for details.
+
+SFN8xxx family adapters provide either inner or outer packet classes.
+If adapter firmware advertises support for tunnels then the PMD
+configures the hardware to report inner classes, and outer classes are
+not reported in received packets.
+However, for VXLAN and GENEVE tunnels the PMD does report UDP as the
+outer layer 4 packet type.
+
+SFN8xxx family adapters report GENEVE packets as VXLAN.
+If UDP ports are configured for only one tunnel type then it is safe to
+treat VXLAN packet type indication as the corresponding UDP tunnel type.
