Pointers to receive-buffer packets sent by Hyper-V are used within the
guest VM.  Hyper-V can send packets with erroneous values or modify
packet fields after they are processed by the guest.  To defend against
these scenarios, copy (sections of) the incoming packet after validating
their length and offset fields in netvsc_filter_receive().  In this way,
the packet can no longer be modified by the host.

I'd have some fixes on top of this and I'm wondering about the process: would
you consider fixes/patches on top of this commit now? would you rather prefer
me to squash these fixes into a v3? other?

Thanks,
