i40iw: Use correct src address in memcpy to rdma stats counters

2017-01-09T07:22:00Z

commit 91c42b72f8e8b45961ff05a05009b644e6316ca2 upstream. hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats(). Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats data into rdma_hw_stats counters.

commit 2b16056f845207967a32497f41cf92b57849f934 upstream. Remove IS_ERR check from caching code as the function being called does not actually return error pointers.

commit dbaaff2a2caa03d472b5cc53a3fbfd415c97dc26 upstream. When an internal error condition is detected, make sure to set the device inactive after dispatching the event so ULPs can get a notification of this event.

IB/mlx5: Use cache line size to select CQE stride

2016-11-26T08:56:58Z

commit 16b0e0695a73b68d8ca40288c8f9614ef208917b upstream. When creating kernel CQs use 128B CQE stride if the cache line size is 128B, 64B otherwise. This prevents multiple CQEs from residing in a 128B cache line, which can cause retries when there are concurrent read and writes in one cache line. Tested with IPoIB on PPC64, saw ~5% throughput improvement.
