As in netvsc_xmit_completion() this must be coded as:
skb = (struct sk_buff *) (unsigned long)packet->send_completio
We send packets using a copy-free mechanism (this is the Guest to Host transport
via VMBUS). While this is obviously optimal for large packets,
it may not be optimal for small packets. Hyper-V host supports
a second mechanism for sending packets that is "copy based". We implement that
mechanism in
