[dpdk-stable] [PATCH 1/2] net/mlx5: fix shared inner RSS

[Matan Azrad]

From: Xiaoyu Min
> The shared RSS action use the _tunnel_ information which is derived from flow
> items to decide whether need to do inner RSS or not.
> However, inner RSS should be decided by RSS level (>1) in configuration and
> then to create TIR with 'IBV_RX_HASH_INNER' hash bit set.
> 
> Also, for one shared RSS action there is only one set of TIRs - outer or inner
> could be so the unnecessary set of TIRs are removed in order to reduce
> resource.
> 
> Fixes: d2046c09aa64 ("net/mlx5: support shared action for RSS")
