Fixes & Enhancements

- Fixed an issue that could cause a crash when the PF miniport driver did not wait for all previously indicated receive packets to return to the miniport from the VPort.
- Fixed an issue where the ND provider threw an exception when an invalid parameter was used.
- Fixed an issue where RSS counters were incorrectly incremented for encapsulated traffic.
- Fixed an issue in the getConnectionData method, where the pcbPrivateData did not return the correct value in case the pPrivateData buffer value was lower than required.
- Fixed an issue that caused an installation failure when running in modify mode with the ADDLOCAL=All parameter.
- Removed an incorrect event log message in VMQ NIC switch mode.
- Fixed an high stress issue that caused uncontrolled memory consumption, sporadic miniport device resets and missing send completion.
- Fixed an issue where the shortcut to the system snapshot tool was broken and pointed to the wrong folder.
- Moved SR-IOV VF's live migration from Beta level to full support of all flows
- Removed a limitation that did not allow both of the following Ethertypes to be enabled at the same time:
0x8906 - Fibre Channel over Ethernet (FCoE)
0x8914 - FCoE Initialization Protocol
- Updated the Cnp_dscp changeable values to 0-63, as supported by the firmware

- Diagnostics - Added 3 diagnostic counters: Send queues priority counter, Current queues under processor handle counter, Total queues under processor handle counter.

- RDMA - Added NDK (Network Direct Kernel) v3 support.
- RDMA - Enabled by default RDMA in the VF from the host, using the EnableguestRdma registry key.
