The line count of the files are different.

It's much more difficult to see what if anything has changed
between the two versions.

trivia:

All the message logging uses of dev_<level> should have
a terminating newline "\n" in netvsc.c

In netvsc.c dev_<level> messages are used.
In netvsc_drv.c netdev_<level> messages are used.

int netvsc_recv_callback(struct hv_device *device_obj,
                               struct hv_netvsc_packet *packet)
{
       struct net_device *net = dev_get_drvdata(&device_obj->device);

Maybe use the netdev_<level> style everywhere possible?

It's odd and a bit ugly to use #include "../../staging/hyperv.h"

Maybe add another include path to the Makefile and just use
#include "hyperv.h"
until all of the hyperv files are moved out of staging?
