====================
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.
