Saeed Mahameed says: ==================== mlx5e-updates-2018-05-17 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.
