[PATCH] doc: update ODM dmadev guide

[Anoob Joseph]

Update ODM dmadev guide with details on ODM PF driver application. The
kernel PF driver module is being removed and so the steps specific to
that is also removed.

 Device Setup
 ------------
 
-ODM DMA device is initialized by kernel PF driver.
-The PF kernel driver is part of Marvell software packages for Odyssey.
+The ODM DMA device is initialized by the ODM PF driver application, which is
+responsible for configuring the device and creating VFs.
 
-Kernel module can be inserted as in below example::
+The driver can be downloaded from GitHub using the following link
+`<https://github.com/MarvellEmbeddedProcessors/odm_pf_driver>`_
 
-   sudo insmod odyssey_odm.ko
-
-ODM DMA device can support up to 16 VFs::
-
-   sudo echo 16 > /sys/bus/pci/devices/0000\:08\:00.0/sriov_numvfs
-
-Above command creates 16 VFs with 2 queues each.
+Instructions for enabling the ODM PF driver are provided in the repository's
+README file.
 
 The ``dpdk-devbind.py`` script, included with DPDK,
 can be used to show the presence of supported hardware.
