The ring_cookie is 64 bits wide which is much larger than can be used
for actual queue index values. So provide some helper routines to
pack a VF index into the cookie. This is useful to steer packets to
a VF ring without having to know the queue layout of the device.
So this patch comes to generalize the proprietary solution introduced
in the below commit?
Well I developed it in a bit different context, but I would expect
the same mechanism to be used for i40e and any other devices that can
support this.

i40e: Add support to program FDir SB rules for VF from PF through ethtool
With this patch we can now add Flow director Sideband rules for a VF from
it's PF. Here is an example on how it can be done when VF id = 5 and
queue = 2:
"ethtool -N ethx flow-type udp4 src-ip x.x.x.x dst-ip y.y.y.y
src-port p1 dst-port p2 action 2 user-def 5"
User-def specifies VF id and action specifies queue.
