The FM10K poll mode driver library provides support for the Intel FM10000
(FM10K) family of 40GbE/100GbE adapters.
+FTAG Based Forwarding of FM10K
+------------------------------
+FTAG Based Forwarding is a unique feature of FM10K. The FM10K family of NICs
+support the addition of a Fabric Tag (FTAG) to carry special information.
+The FTAG is placed at the beginning of the frame, it contains information such
+as where the packet comes from and goes, the vlan tag. In FTAG based forwarding
+mode, the switch logic forwards packets according to glort (global resource tag)
+information, other than the mac and vlan table. Now this feature works only on
+PF.
+
+To enable this feature, turn CONFIG_RTE_LIBRTE_FM10K_FTAG_FWD to y in the
+configuration file. A unit test case fm10k_ftag_autotest is for reference, it shows
+how to read sglort info on RX and how to make an FTAG on TX.
