+OCTEON TX EP Poll Mode driver
+===========================
+
+The OCTEON TX EP ETHDEV PMD (**librte_pmd_octeontx_ep**) provides poll mode
+ethdev driver support for the virtual functions (VF) of **Marvell OCTEON TX2**
+and **Cavium OCTEON TX** families of adapters in SR-IOV context.
+
+More information can be found at `Marvell Official Website
+<https://www.marvell.com/content/dam/marvell/en/public-collateral/embedded-processors/marvell-liquidio-III-solutions-brief.pdf>`_.
+
+
+Prerequisites
+-------------
+
+This driver relies on external kernel PF driver for resources allocations
+and initialization. The following dependencies are not part of DPDK and
+must be installed separately:
+
+- **Kernel module**
+  This module, octeon_drv, drives the physical function, initializes hardware,
+  allocates resources such as number of VFs, input/output queues for itself and
+  the number of i/o queues each VF can use.
+
+See :doc:`../platform/octeontx2` for SDP interface information which provides PCIe endpoint support for a remote host.
