'include/linux/net/intel' seems fine to me. I agree with moving
virtchnl.h there since it is quite clear that any historical ambitions
about AVF being vendor agnostic are long dead, so having it in its own
'non-intel' folder is silly.
Strictly speaking, I think the goal of moving the files is due to the
fact that a lot of the core ixd code is not really network layer but
instead PCI layer.
