| | * mlx4_core: restore optimal ICM memory allocationEric Dumazet2018-06-031-6/+12

The big one is an additional cost of 256 bytes of overhead per 4096 bytes, or 6.25 % which is unacceptable since ICM can be pretty large. This comes from having to allocate one struct mlx4_icm_chunk (256 bytes) per MLX4_TABLE_CHUNK, which the buggy commit shrank to 4KB (instead of prior 256KB) Note that mlx4_alloc_icm() is already able to try high order allocations and fallback to low-order allocations under high memory pressure. Most of these allocations happen right after boot time, when we get plenty of non fragmented memory, there is really no point being so pessimistic and break huge pages into order-0 ones just for fun. We only have to tweak gfp_mask a bit, to help falling back faster, without risking OOM killings. Second regression is an KASAN fault, that will need further investigations.

| * | mlxsw: spectrum_span: Suppress VLAN on BRIDGE_VLAN_INFO_UNTAGGEDPetr Machata2018-06-041-1/+3

After the packet path is resolved to a particular bridge egress device, flags on packet VLAN determine whether the egressed packet should be tagged. The current logic however only ever sets the VLAN tag, never suppresses it. Thus if there's a VLAN netdevice above the bridge that determines the packet VLAN, that VLAN is never unset, and mirroring is configured with VLAN tagging. Fix by setting the packet VLAN on both branches: set to zero (for unset) when BRIDGE_VLAN_INFO_UNTAGGED, copy the resolved VLAN (e.g. from bridge PVID) otherwise.

Whenever possible, prefer using a linear SKB, and build it wrapping the WQE buffer. Otherwise (for example, jumbo frames on x86), use non-linear SKB, with as many frags as needed. In this case, multiple WQE scatter entries are used, up to a maximum of 4 frags and 10KB of MTU. This implied to remove support of HW LRO in legacy RQ, as it would require large number of page allocations and scatter entries per WQE on archs with PAGE_SIZE = 4KB, yielding bad performance. In earlier patches, we guaranteed that all completions are in-order, and that we use a cyclic WQ. This creates an oppurtunity for a performance optimization: The mapping between a "struct mlx5e_dma_info", and the WQEs (struct mlx5e_wqe_frag_info) pointing to it, is constant across different cycles of a WQ. This allows initializing the mapping in the time of RQ creation, and not handle it in datapath. A struct mlx5e_dma_info that is shared between different WQEs is allocated by the first WQE, and freed by the last one. This implies an important requirement: WQEs that share the same struct mlx5e_dma_info must be posted within the same NAPI. Otherwise, upon completion, struct mlx5e_wqe_frag_info would mistakenly point to the new struct mlx5e_dma_info, not the one that was posted (and the HW wrote to). This bulking requirement is actually good also for performance reasons, hence we extend the bulk beyong the minimal requirement above. With this memory scheme, the RQs memory footprint is reduce by a factor of 2 on x86, and by a factor of 32 on PowerPC. Same factors apply for the number of pages in a GRO session.

| * | net/mlx5e: RX, Use cyclic WQ in legacy RQTariq Toukan2018-06-026-111/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that LRO is not supported for Legacy RQ, there is no source of out-of-order completions in the WQ, and we can use a cyclic one. This has multiple advantages: - reduces the WQE size (smaller PCI transactions). - lower overhead in datapath (no handling of 'next' pointers). - no reserved WQE for the WQ head (was need in linked-list). - allows using a constant map between frag and dma_info struct, in downstream patch. Performance tests: ConnectX-4, single core, single RX ring. Major gain in packet rate of single ring XDP drop. Bottleneck is shifted form HW (at 16Mpps) to SW (at 20Mpps).

| * | net/mlx5e: RX, Remove HW LRO support in legacy RQTariq Toukan2018-06-022-14/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current LRO implementation in Legacy RQ uses high-order pages. In downstream patches of this series we complete the transition to using only order-0 pages in RX datapath (which was already done in Striding RQ). Unlike the more advanced Striding RQ, Legacy RQ does not make reuse of any non-consumed buffers of non-full LRO sessions, and combining it with order-0 pages has many performance drawbacks. Hence, here we totally remove LRO support in Legacy RQ. This guarantees having no out-of-order completions, which allows using a cyclic work queue (instead of a linked-list) in a downstream patch.

These notifications have orig_dev set to the bridge in question. Because there's no specific support for these VLANs, just ignore the notifications to maintain the current behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, the PCI BAR0 register is used for triggering FW reset. However, that is a legacy attitude and it is recommended to use MRSR to perform reset instead. So do that. Move the reset into init() function as the cmd interface needs to be used. With that, IRQ initialization needs to be moved as well. As a side effect, the reset move simplifies the devlink reload flow.

In the general case, it means that packets are potentially sent to the mirror port before or after some actions were applied on them. To properly do that, we follow on the exact action order as set for the flow and make sure this will also be the case when we program the HW offload. If all the actions should apply before forwarding to the mirror and dest port, mirroring is just multicasting to the two vports. Otherwise, we split the TC flow to two HW rules, where the 1st applies only the actions needed up to the mirror (if there are such) and the 2nd the rest of the actions plus the forwarding to the dest vport. ================= 2) Move to order-0 only allocations (using fragmented work queues) for all work queues used by the driver, RX and TX descriptor rings (RQs, SQs and Completion Queues (CQs)), from Tariq Toukan. 3) Avoid resetting netdevice statistics on netdevice state changes, from Eran Ben Elisha. ==================== Signed-off-by: David S.

With this change, counters will not be reset upon channel configuration changes. Channel's statistics for SQs which are associated with TCs higher than zero will be presented in ethtool -S, only for SQs which were opened at least once since the module was loaded (regardless of their open/close current status). This is done in order to decrease the total amount of statistics presented and calculated for the common out of box use (no QoS). mlx5e_channel_stats is a compound of CH,RQ,SQs stats in order to create locality for the NAPI when handling TX and RX of the same channel. Align the new statistics struct per ring to avoid several channels update to the same cache line at the same time. Packet rate was tested, no degradation sensed.

Plus update channels software statistics on the fly when calling ndo_get_stats64, and remove it from stats periodic work.
