From: Or Gerlitz <ogerlitz@mellanox.com>
 
 This series addresses a regression introduced by the
 shared block TC changes [1]. Currently, for VF->VF and uplink->VF rules, the
 TC core (cls_api) attempts to offload the same flow multiple times into
 the driver, as a side effect of the mlx5 registration to the egdev callback.
 
 We use the flow cookie to ignore attempts to add such flows, we can't
 reject them (return error), b/c this will fail the offload attempt, so we
 ignore that.
 
 The last patch of the series deals with exposing HW stats counters through
 ethtool for the vport reps.
 
 Dave - the regression that we are addressing was introduced in 4.15 [1] and applies
 to nfp and mlx5. Jiri suggested to push driver side fixes to net-next, this is
 already done for nfp [2][3]. Once this is upstream, we will submit a small/point
 single patch fix for the TC core code which can serve for net and stable, but not
 carried into net-next, b/c it might limit some future use-cases.
