It would be useful to retain this igb_uio information. Maybe vfio information should be added too. This comment also applies to the GSG, the differences need to be documented. Regards, Bernard.

Since DPDK now has support for the in-tree uio_pci_generic driver, update the programmers guide document to reference this module, and to use it in preference to the igb_uio driver, which is DPDK-specific.
