This patch enables reading sglort (global resource tag) info into the mbuf for RX and inserting an FTAG (Fabric Tag) at the beginning of the packet for TX. The vlan_tci_outer field selected from rte_mbuf structure for sglort is not used in fm10k now. In FTAG based forwarding mode, the switch will forward packets according to glort info in FTAG rather than mac and vlan table. To activate this feature, user needs to pass a devargs parameter to eal for fm10k device like "-w 0000:84:00.0,enable_ftag=1". Currently this feature is supported only on PF, because FM10K_PFVTCTL register is read-only for VF.
