mlx4_core: Add network flow counters
ConnectX devices support a set of flow counters that can be attached to a set containing one or more QPs. Each such counter tracks receive and transmit packets and bytes of these QPs. This patch queries the device to check support for counters, handles initialization of the HCA to enable counters, and initializes a bitmap allocator to control counter allocations. Derived from patch by Eli Cohen <eli@mellanox.co.il>. Signed-off-by: Or Gerlitz <ogerlitz@mellanox.co.il> Signed-off-by: Roland Dreier <roland@purestorage.com>
