+Linux* Base Driver for Intel(R) Network Connection
+November 24, 2009
+- In This Release
+- Identifying Your Adapter
+- Known Issues/Troubleshooting
+- Support
+In This Release
+This file describes the ixgbevf Linux* Base Driver for Intel Network
+The ixgbevf driver supports 82599-based virtual function devices that can only
+be activated on kernels with CONFIG_PCI_IOV enabled.
+The ixgbevf driver supports virtual functions generated by the ixgbe driver
+with a max_vfs value of 1 or greater.
+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
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+Known Issues/Troubleshooting
+  Unloading Physical Function (PF) Driver Causes System Reboots When VM is
+  Running and VF is Loaded on the VM
+  ------------------------------------------------------------------------
+  Do not unload the PF driver (ixgbe) while VFs are assigned to guests.
+For general information, go to the Intel support website at:
+or the Intel Wired Networking project hosted by Sourceforge at:
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to
+Intel 10 Gigabit Linux driver.
