From f2a3f6a32cf64db1495b5ced8625b9a80bde44e5 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Wed, 15 Jun 2011 14:47:14 +0000 Subject: 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 .
