* bnxt_en: Fix to include flow direction in L2 keySomnath Kotur2019-08-182-5/+5
| | | | | | | | | | | | | | | | | | | | | FW expects the driver to provide unique flow reference handles for Tx or Rx flows. When a Tx flow and an Rx flow end up sharing a reference handle, flow offload does not seem to work. This could happen in the case of 2 flows having their L2 fields wildcarded but in different direction. Fix to incorporate the flow direction as part of the L2 key v2: Move the dir field to the end of the bnxt_tc_l2_key struct to fix the warning reported by kbuild test robot <lkp@intel.com>. There is existing code that initializes the structure using nested initializer and will warn with the new u8 field added to the beginning. The structure also packs nicer when this new u8 is added to the end of the structure [MChan]. Fixes: abd43a13525d ("bnxt_en: Support for 64-bit flow handle.")

* bnxt_en: Use correct src_fid to determine direction of the flowVenkat Duvvuru2019-08-181-3/+1Star
| | | | | | | | | | | | | | | | | | | Direction of the flow is determined using src_fid. For an RX flow, src_fid is PF's fid and for TX flow, src_fid is VF's fid. Direction of the flow must be specified, when getting statistics for that flow. Currently, for DECAP flow, direction is determined incorrectly, i.e., direction is initialized as TX for DECAP flow, instead of RX. Because of which, stats are not reported for this DECAP flow, though it is offloaded and there is traffic for that flow, resulting in flow age out. This patch fixes the problem by determining the DECAP flow's direction using correct fid. Set the flow direction in all cases for consistency even if 64-bit flow handle is not used.

* bnxt_en: Improve RX doorbell sequence.Michael Chan2019-08-181-3/+7
| | | | | | | | | | | | | | | | | | When both RX buffers and RX aggregation buffers have to be replenished at the end of NAPI, post the RX aggregation buffers first before RX buffers. Otherwise, we may run into a situation where there are only RX buffers without RX aggregation buffers for a split second. This will cause the hardware to abort the RX packet and report buffer errors, which will cause unnecessary cleanup by the driver. Ringing the Aggregation ring doorbell first before the RX ring doorbell will prevent some of these buffer errors. Use the same sequence during ring initialization as well.

| | | | | | | | | | | | | | | During device shutdown, the VNIC clearing sequence needs to be modified to free the VNIC first before freeing the RSS contexts. The current code is doing the reverse and we can get mis-directed RX completions to CP ring ID 0 when the RSS contexts are freed and zeroed. The clearing of RSS contexts is not required with the new sequence. Refactor the VNIC clearing logic into a new function bnxt_clear_vnic() and do the chip specific VNIC clearing sequence.

| | | | | | | | | | | | | | | | | | | | | | | Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.

In the PCI shutdown method, we need to call pci_disable_device() to shutdown DMA to prevent this DMA before we put the device into D3hot.

We want a similar functionality for other protocols, which might need to optimize interrupts differently. Main motivation here is DIM for NVMf storage protocol. Current DIM implementation prioritizes reducing interrupt overhead over latency. Also, in order to reduce DIM's own overhead, the algorithm might take some time to identify it needs to change profiles. While this is acceptable for networking, it might not work well on other scenarios. Here we propose a new structure to DIM. The idea is to allow a slightly modified functionality without the risk of breaking Net DIM behavior for netdev. We verified there are no degradations in current DIM behavior with the modified solution. Suggested solution: - Common logic is implemented in lib/dim/dim.c - Net DIM (existing) logic is implemented in lib/dim/net_dim.c, which uses the common logic in dim.c - Any new DIM logic will be implemented in "lib/dim/new_dim.c". This new implementation will expose modified versions of profiles, dim_step() and dim_decision(). - DIM API is declared in include/linux/dim.h for all implementations. Pros for this solution are: - Zero impact on existing net_dim implementation and usage - Relatively more code reuse (compared to two separate solutions) - Increased extensibility ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | bnxt_need_reserve_rings() determines if any resources have changed and requires new reservation with firmware. The NQ checking is currently just an approximation. Improve the NQ checking logic to make it accurate. NQ reservation is only needed on 57500 PFs. This fix will eliminate unnecessary reservations and will reduce NQ reservations when some NQs have been released on 57500 PFs.
