This change adds
hw_countersto the existing infiniband class so that additional counter information for infiniband devices can be obtained.In preparing this PR, I have confirmed that
hw_countersfor Infiniband devices can be obtained from themlx5_corekernel module included in multiple Linux distributions and multiple OS versions.I have also confirmed that it is possible to get
hw_countersfrom themlx5_corekernel module included in the OFED driver.However, I have not checked for other cases (e.g. mlx4_core), so this implementation is limited to mlx5 only.
