Merge branch 'mlxsw-tc-flower-offload-stats'
Jiri Pirko says: ==================== mlxsw: Add support for TC flower offload statistics Arkadi says: This patchset adds support for retrieving TC flower statistics for offloaded rules, which includes packets count, bytes count and last used time stamp. Currently The statistics are gathered on a per-rule basis. This patchset also includes generic allocator for counters. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
