Due to migration of servers to cloud computing, we bought several NICs that support mechanisms like SRIOV and VMDQ. Furthermore, as security risk was also a concern and we did not want to create more overhead on the processor, IPSec Offload support was essential.

The model chosen was: Intel Gigabit ET2 Quad Port Svr Adptr. (With 82576GB controller): http://ark.intel.com/products/49187/intel-gigabit-et2-quad-port-server-adapter

However, we were unable to configure IPSec Offload on Linux. We tried to test on another server we have, a Windows Server 2012 R2, but again without success. It seems that the driver for this controller is not available for windows server 2012 R2, and Linux.

The test on windows would be only for verification purposes, we will not use this platform.

Could someone confirm this lack of support for Linux?
