* net/mlx5e: Re-work TIS creation functionsTariq Toukan2019-07-061-0/+2
| | | | | | | | | | | | Let the EN TIS creation function (mlx5e_create_tis) be responsible for applying common mdev related fields. Other specific fields must be set by the caller and passed within the inbox.

|\ | | | | | | | | | | | | | | | | | | | | | | | | net/sched/cls_api.c has overlapping changes to a call to nlmsg_parse(), one (from 'net') added rtm_tca_policy instead of NULL to the 5th argument, and another (from 'net-next') added cb->extack instead of NULL to the 6th argument. net/ipv4/ipmr_base.c is a case of a bug fix in 'net' being done to code which moved (to mr_table_dump)) in 'net-next'. Thanks to David Ahern for the heads up. Signed-off-by: David S. Miller <davem@davemloft.net>
| * net/mlx5: WQ, fixes for fragmented WQ buffers APITariq Toukan2018-10-111-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mlx5e netdevice used to calculate fragment edges by a call to mlx5_wq_cyc_get_frag_size(). This calculation did not give the correct indication for queues smaller than a PAGE_SIZE, (broken by default on PowerPC, where PAGE_SIZE == 64KB). Here it is replaced by the correct new calls/API. Since (TX/RX) Work Queues buffers are fragmented, here we introduce changes to the API in core driver, so that it gets a stride index and returns the index of last stride on same fragment, and an additional wrapping function that returns the number of physically contiguous strides that can be written contiguously to the work queue. This obsoletes the following API functions, and their buggy usage in EN driver: * mlx5_wq_cyc_get_frag_size() * mlx5_wq_cyc_ctr2fragix() The new API improves modularity and hides the details of such calculation for mlx5e netdevice and mlx5_ib rdma drivers. New calculation is also more efficient, and improves performance as follows: Packet rate test: pktgen, UDP / IPv4, 64byte, single ring, 8K ring size.

| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a helper init/cleanup function that initializes mlx5e generic netdev private structure, and use them from all profiles init/cleanup callbacks.

* net/mlx5e: TX, Use actual WQE size for SQ edge fillTariq Toukan2018-05-251-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | We fill SQ edge with NOPs to avoid WQEs wrap. Here, instead of doing that in advance for the maximum possible WQE size, we do it on-demand using the actual WQE size. We re-order some parts in mlx5e_sq_xmit to finish the calculation of WQE size (ds_cnt) before doing any writes to the WQE buffer. When SQ work queue is fragmented (introduced in an downstream patch), dealing with WQE wraps becomes more frequent. This change would drastically reduce the overhead in this case.

| | | | | | | | | | Resources such as FT, QPN HT and mdev resources should be allocated only by parent netdev. Shared resources are allocated and freed by the parent interface since the parent is always present and created before the IPoIB PKEY sub-interface.

| | | | | | | | | | Similar to VLAN interfaces child interfaces have limited ethtool support. In current code the main limitation that does not allow child interface ethtool configuration is due to shared resources which are managed by the parent.

| | | | | | | | | | | | Child interface profile will be called to support child interface specific behaviour. The child code is sparse compared to the parent since the RX channels are shared between the interfaces. Creating a septate profile for child and parent will make a smother code with a better ability for future expansion. The profile stuct is exposed to the parent using a getter function.

* net/mlx5e: IPoIB, Use hash-table to map between QPN to child netdevAlex Vesker2017-10-141-0/+12
| | | | | | | | | | | | | This change is needed for PKEY support, since the RQs are shared between the child interface and the parent. The parent is responsible for NAPI and the precessing of RX completions. Using the dqpn in the completion descriptor we set the corresponding child IPoIB netdevice on the SKB. The mapping between the dqpn and the netdevice is done using a HT, each mlx5 IPoIB interface registers its mapping on creation.
