The L2-level steering (classification based on MAC address or VLAN) is
what determines
the grouping.
If the hardware supports steering to N individual rings, then the
drivers should register
N groups with 1 ring in each. If the hardware cannot offer L2 steering
at all, then
it is a single group encompassing all the rings on the system.
Back to the specific question, there is always 1 group, at least. the
software in the framework
will no emulate the multiple rings.
