Bug#767261: xen-netback changes in #767261 break Mini-OS netfront

[Gedalya <gedalya@gedalya.net>]

Hi Ian!

Thank you so much for building this kernel!

I just had this problem with a Windows 2012 R2 domu with GPLPV drivers 
from http://www.ejbdigital.com.au/1-0-1105/.
dom0 has the message:
[  324.272925] vif vif-5-0: 22 feature-rx-notify is mandatory
domu obviously has nothing helpful to say ;-)
With your newly built kernel, everything seems to be fine.

Cheers!
