Re: [PATCH net-next 0/2] ntuple filters with RSS

This series introduces the ability to mark an ethtool steering filter to use
 RSS spreading, and the ability to create and configure multiple RSS contexts
 with different indirection tables, hash keys, and hash fields.
An implementation for the sfc driver (for 7000-series and later SFC NICs) is
 included in patch 2/2.

The anticipated use case of this feature is for steering traffic destined for
 a container (or virtual machine) to the subset of CPUs on which processes in
 the container (or the VM's vCPUs) are bound, while retaining the scalability
 of RSS spreading from the viewpoint inside the container.
The use of both a base queue number (ring_cookie) and indirection table is
 intended to allow re-use of a single RSS context to target multiple sets of
 CPUs.  For instance, if an 8-core system is hosting three containers on CPUs
 [1,2], [3,4] and [6,7], then a single RSS context with an equal-weight [0,1]
 indirection table could be used to target all three containers by setting
 ring_cookie to 1, 3 and 6 on the respective filters.

The postings for this series didn't make it to the netdev list for some
reason, could you please resend?

Thank you.
