Pointers to ring-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, return a copy of the incoming VMBus packet
after validating its length and offset fields in hv_pkt_iter_first().
In this way, the packet can no longer be modified by the host.

Andrea -- has anything changed in this version of this patch, except
the value of NETVSC_MAX_XFER_PAGE_RANGES?  It used to be a
fixed 375, but now is NVSP_RSC_MAX, which is 562.

If that's the only change, then

The only change here is indeed the value of NETVSC_MAX_XFER_PAGE_RANGES,
apologies for the omission of the changelog.

Thanks for the review.
