Would it be better in the long term to make the transmit indirection
table available under the new rt_netlink based API's for ethtool?

I can imagine that other hardware or hypervisors might have the
same kind of transmit mapping.

Alternatively, the hyperv network driver could integrate/replace the
indirection table with something based on current receive flow steering.
