In sfc driver one RX queue per physical core was allocated by default.
Later on, IRQ affinities were set spreading the IRQs in all NUMA local
CPUs.

However, with that default configuration it result in a non very optimal
configuration in many modern systems. Specifically, in systems with hyper
threading and 2 NUMA nodes, affinities are set in a way that IRQs are
handled by all logical cores of one same NUMA node. Handling IRQs from
both hyper threading siblings has no benefit, and setting affinities to one
queue per physical core is neither a very good idea because there is a
performance penalty for moving data across nodes (I was able to check it
with some XDP tests using pktgen).

Here is the summary with links:
  - [v2,net-next,1/2] sfc: default config to 1 channel/core in local NUMA node only
    (no matching commit)
  - [v2,net-next,2/2] sfc: set affinity hints in local NUMA node only

You are awesome, thank you!
