mechanism to report failure when it happens.

1ce09e899d hyperv: Add support for setting MAC from within guests
This adds support for setting synthetic NIC MAC address from within Linux
guests. Before using this feature, the option "spoofing of MAC address"
should be enabled at the Hyper-V manager / Settings of the synthetic
NIC.

Thanks to Kin Cho <kcho@infoblox.com> for the initial implementation and
tests. And, thanks to Long Li <longli@microsoft.com> for the debugging
works.

7591157e18 usb/net: rndis: break out <linux/rndis.h> defines
As a first step to consolidate the RNDIS implementations, break out
a common file with all the #defines and move it to <linux/rndis.h>.

This also deletes the immediate duplicated defines in the
<linux/rndis.h> file that yields a lot of compilation warnings.

453263421f net/hyperv: Remove unnecessary kmap_atomic in netvsc driver
__get_free_pages() doesn't return HI memory, so the memory is always mapped.
kmap_atomic() is not necessary here. This patch removes the kmap_atomic()
calls and related code for locking and page manipulation.
