I40E Poll Mode Driver
======================
- VF Daemon (VFD) - EXPERIMENTAL
- Dynamic Device Personalization (DDP)
- Queue region configuration
+- Vitrual Function Port Representors
Prerequisites
-------------
1, 2, 4, 8 or 16. If no such parameter is configured, the number of queues
per VF is 4 by default.
+- ``Support multiple driver`` (default ``disable``)
+
+ There was a multiple driver support issue during use of 700 series Ethernet
+ Adapter with both Linux kernel and DPDK PMD. To fix this issue, ``devargs``
+ parameter ``support-multi-driver`` is introduced, for example::
+
+ -w 84:00.0,support-multi-driver=1
+
+ With the above configuration, DPDK PMD will not change global registers, and
+ will switch PF interrupt from IntN to Int0 to avoid interrupt conflict between
+ DPDK and Linux Kernel.
+
+- ``Support VF Port Representor`` (default ``not enabled``)
+
+ The i40e PF PMD supports the creation of VF port representors for the control
+ and monitoring of i40e virtual function devices. Each port representor
+ corresponds to a single virtual function of that device. Using the ``devargs``
+ option ``representor`` the user can specify which virtual functions to create
+ port representors for on initialization of the PF PMD by passing the VF IDs of
+ the VFs which are required.::
+
+ -w DBDF,representor=[0,1,4]
+
+ Currently hot-plugging of representor ports is not supported so all required
+ representors must be specified on the creation of the PF.
Driver compilation and testing
------------------------------
Current implementation supports MPLSoUDP/MPLSoGRE/GTP-C/GTP-U/PPPoE/PPPoL2TP,
steering can be used with rte_flow API.
