> Subject: [Intel-wired-lan] [PATCH] ethtool: support queue and vf fields for
> rxclass filters
> 
> Recent kernels have made it possible to specify filters applying to
> a virtual function by partitioning the ring_cookie (action) value. The
> lower 32bits will represent the queue, while the next 8bits represent
> the virtual function.
> 
> Add support to view and specify the ring_cookie in this way so that
> users do not have to manually create action values, and don't need to
> understand the underlying layout of the ring_cookie value.
> 
> Support using queue and vf fields which will fill in their specific bits
> of the ring_cookie value, using new customized OPT_RING_VF and
> OPT_RING_QUEUE.
> 
> Add support to display the ring cookie value as a split VF identifier
> and queue.
