6. New Features and Changes From MLNX_EN 1.3
===============================================================================
- VPI support
- ETH driver improvements

===============================================================================
7. Known Issues 
===============================================================================
The following is a list of general limitations and known issues of the various
components included in this Mellanox WinOF VPI for Windows release.

- Raptor cards requires FW ver. 2.7.700 or higher

- This release does not support installing both Mellanox WinOF VPI(or other IB
  drivers) and Mellanox's Ethernet software stack (the MLNX_EN for Windows
  package).

- Windows 2008 installation: If UAC is enabled, installing MSI packages 
  using a double-click does not lead to a correct installation (though it may
  be indicated that the installation succeeded).
  A workaround for this issue is to install the MSI package from the command
  line with administrator privileges. Enter:
  msiexec.exe /i MLNX_WinOF_<arch>_<version>.msi

- All previous versions of IB/ETH drivers must be uninstalled before
  installing this driver

- Uninstall requires rebooting the machine to complete the uninstall process


- Current release does not support in-band burning with WinMFT
