From: Majd Dibbiny Date: Wed, 18 Jan 2017 13:25:10 +0000 (+0200) Subject: IB/mlx5: Add port counter support for Receive WQs X-Git-Tag: v4.14-rc1~1433^2~26 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=23a6964e3adb0796e1633562a574839b92360cb6;p=platform%2Fkernel%2Flinux-rpi.git IB/mlx5: Add port counter support for Receive WQs Counters weren't updated due to Receive WQs' traffic since the counter-id was not associated with the RQ. Added support for associating the q-counter-id with the Receive WQ. The attachment is done only when changing WQ's state from RESET to READY in modify-WQ command. FW support is required for the above, without this support Receive WQ counters will not count.
