+Subject: staging: hv: Fix missing functions for net_device_ops
+
+From: Haiyang Zhang <haiyangz@microsoft.com>
+
+commit b681b5886bb5d1f5b6750a0ed7c62846da7ccea4 upstream.
+
+Fix missing functions for net_device_ops.
+It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27,
+the default functions for Ethernet, like eth_change_mtu(), were assigned
+by ether_setup(). But in 2.6.32, these function pointers moved to
+net_device_ops structure and no longer be assigned in ether_setup(). So
+we need to set these functions in our driver code. It will ensure the
+MTU won't be set beyond 1500. Otherwise, this can cause an error on the
+server side, because the HyperV linux driver doesn't support jumbo frame
+yet.

+commit 0c47a70a9a8a6d1ec37a53d2f9cb82f8b8ef8aa2 upstream.
+
+Fixed bounce offset kmap problem by using correct index.
+The symptom of the problem is that in some NAS appliances this problem
+represents Itself by a unresponsive VM under a load with many clients writing
+small files.

+Subject: staging: hv: Fixed the value of the 64bit-hole inside ring buffer
+
+From: Haiyang Zhang <haiyangz@microsoft.com>
+
+commit e5fa721d1c2a54261a37eb59686e18dee34b6af6 upstream.
+
+Fixed the value of the 64bit-hole inside ring buffer, this
+caused a problem on Hyper-V when running checked Windows builds.
+
+Checked builds of Windows are used internally and given to external
+system integrators at times. They are builds that for example that all
+elements in a structure follow the definition of that Structure. The bug
+this fixed was for a field that we did not fill in at all (Because we do
+Not use it on the Linux side), and the checked build of windows gives
+errors on it internally to the Windows logs.
+
+This fixes that error.

+Subject: staging: hv: Increased storvsc ringbuffer and max_io_requests
+
+From: Hank Janssen <hjanssen@microsoft.com>
+
+commit 15dd1c9f53b31cdc84b8072a88c23fa09527c596 upstream.
+
+Increased storvsc ringbuffer and max_io_requests. This now more
+closely mimics the numbers on Hyper-V. And will allow more IO requests
+to take place for the SCSI driver.
+
+Max_IO is set to double from what it was before, Hyper-V allows it and
+we have had appliance builder requests to see if it was a problem to
+increase the number.
+
+Ringbuffer size for storvsc is now increased because I have seen A few buffer
+problems on extremely busy systems. They were Set pretty low before.
+And since max_io_requests is increased I Really needed to increase the buffer
+as well.
