2016-09-22net/mlx5e: Union RQ RX info per RQ typeSaeed Mahameed3-26/+30
We have two types of RX RQs, and they use two separate sets of info arrays and structures in RX data path function. Today those structures are mutually exclusive per RQ type, hence one kind is allocated on RQ creation according to the RQ type. For better cache locality and to minimalize the sizeof(struct mlx5e_rq), in this patch we define them as a union.

2016-09-22net/mlx5e: Build RX SKB on demandSaeed Mahameed3-123/+133
For non-striding RQ configuration before this patch we had a ring with pre-allocated SKBs and mapped the SKB->data buffers for device. For robustness and better RX data buffers management, we allocate a page per packet and build_skb around it. This patch (which is a prerequisite for XDP) will actually reduce performance for normal stack usage, because we are now hitting a bottleneck in the page allocator. We use the page-cache to restore or even improve performance in comparison to the old RX scheme. Packet rate performance testing was done with pktgen 64B packets on xmit side and TC ingress dropping action on RX side. CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz Comparison is done between: 1.Baseline, before 'net/mlx5e: Build RX SKB on demand' 2.Build SKB with RX page cache (This patch) RX Cores Baseline Build SKB+page-cache Improvement ----------------------------------------------------------- 1 4.16Mpps 5.33Mpps 28% 2 7.16Mpps 10.24Mpps 43% 4 13.61Mpps 20.51Mpps 51% 8 25.32Mpps 32.00Mpps 26% All respective cores were 100% utilized.

2016-09-21net/mlx4_core: Fix deadlock when switching between polling and event fw commandsJack Morgenstein2-6/+19
When switching from polling-based fw commands to event-based fw commands, there is a race condition which could cause a fw command in another task to hang: that task will keep waiting for the polling sempahore, but may never be able to acquire it. This is due to mlx4_cmd_use_events, which "down"s the sempahore back to 0. During driver initialization, this is not a problem, since no other tasks which invoke FW commands are active. However, there is a problem if the driver switches to polling mode and then back to event mode during normal operation. The "test_interrupts" feature does exactly that. Running "ethtool -t <eth device> offline" causes the PF driver to temporarily switch to polling mode, and then back to event mode. (Note that for VF drivers, such switching is not performed). Fix this by adding a read-write semaphore for protection when switching between modes.
