Documentation: ixgbevf: Prepare documentation for RST conversion

Before making the conversion to the RST (reStructured Text) format, there
are changes needed to the documentation so that there are no build errors.

Also fixed old/broken URLs to the correct or updated URL.

-This file describes the ixgbevf Linux* Base Driver for Intel Network
-Connection.
-
-The ixgbevf driver supports 82599-based virtual function devices that can only
-be activated on kernels with CONFIG_PCI_IOV enabled.
+This driver supports 82599, X540, X550, and X552-based virtual function devices
+that can only be activated on kernels that support SR-IOV.
 
-The ixgbevf driver supports virtual functions generated by the ixgbe driver
-with a max_vfs value of 1 or greater.
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel adapter. All hardware requirements listed apply to use
+with Linux.
 
-The guest OS loading the ixgbevf driver must support MSI-X interrupts.
-
-VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs.
 
 Identifying Your Adapter
 ========================
+The driver is compatible with devices based on the following:

 Known Issues/Troubleshooting
 ============================
 
+SR-IOV requires the correct platform and OS support.
+
+The guest OS loading this driver must support MSI-X interrupts.
+
+This driver is only supported as a loadable module at this time. Intel is not
+supplying patches against the kernel source to allow for static linking of the
+drivers.
+
+VLANs: There is a limit of a total of 64 shared VLANs to 1 or more VFs.
