2017-09-03net/mlx5e: Distribute RSS table among all RX ringsTariq Toukan3-17/+4
In default, uniformly distribute the RSS indirection table entries among all RX rings, rather than restricting this only to the rings on the close NUMA node. irqbalancer would anyway dynamically override the default affinities set to the RX rings. This gives better multi-stream performance and CPU util. Signed-off-by: Tariq Toukan <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
2017-09-03net/mlx5e: Stop NAPI when irq balancer changes affinityTariq Toukan3-2/+26
NAPI context keeps rescheduling on same CPU as long as it's busy. This doesn't give the oppurtunity for changes in irq affinities to take effect. Fix that by calling napi_complete_done() upon a change in affinity. This would stop the NAPI and reschedule it on the new CPU.

2017-09-03net/mlx5e: Use kernel's mechanism to avoid missing NAPIsTariq Toukan3-15/+1
We used a channel state bit MLX5E_CHANNEL_NAPI_SCHED to make sure no NAPI is missed when a channel's napi_schedule() is called for completion events of the different channel's resources/rings while NAPI is currently running. Now, as similar mechanism is implemented in kernel, ("39e6c8208d7b net: solve a NAPI race"), we obsolete our own implementation and rely on the return value of napi_complete_done(). This patch removes a redundant overhead of atomic bit operations.

2017-09-03net/mlx5e: Slightly increase RX page-cache sizeTariq Toukan1-1/+1
In XDP_TX flow, we now get back quicker to each page in page-cache, and on some occasions refcount does not get back to 1 on time, causing some costly page allocations. Slightly increase the size of RX page-cache to significantly decrease the chances for this to happen. Signed-off-by: Tariq Toukan <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>

2017-09-03net/mlx5e: Remove unnecessary fields in ICO SQTariq Toukan3-26/+2
As of current design, in each NAPI, only a single UMR WQE completion could be available in the completion queue of the the internal control operations (ICO) send queue, in addition to nop operations that require no actions upon completion. This renders the consume index obsolete, as the wqe_counter field in CQE is sufficient. This helps removing a memory barrier, and obsoletes the need for tracking the num_wqebbs to update the consumer counter. In addition, remove other unused fields in icosq struct: pdev, dma_fifo_pc, and prev_cc. Signed-off-by: Tariq Toukan <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
2017-09-03net/mlx5e: Type-specific optimizations for RX post WQEs functionTariq Toukan4-87/+92

2017-09-03net/mlx5e: Non-atomic RQ state indicator for UMR WQE in progressTariq Toukan3-7/+8
The indication for a UMR WQE in progress is needed only within the NAPI context, and hence no races possible and no need for the use of atomic operations. The only place the flag is read outside of NAPI context is in closure flow, after RQ is disabled flag is no more accessed in NAPI. Use a boolean instead of a bit in ring state, so that its non-atomic set operations do not race with the atomic sets of the other bits.

2017-09-03net/mlx5e: Non-atomic indicator for ring enabled stateTariq Toukan5-8/+10
Rings enabled state change occurs in control path only, and is always followed by a napi_sychronize(), so that following NAPIs read the new value. This read does not need to be atomic. The RQ auto-moderation bit is not set/cleared in data-path. No need for atomic read, a regular read operation is sufficient. In RQ creation time as well, there's no multiple threads trying to access it yet, hence a regular read can be used.

2017-09-03net/mlx5e: Early-return on empty completion queuesTariq Toukan2-24/+32
NAPI context handles different kinds of completion queues (RX, TX, and others). Hence, upon a poll trial, some of them might be empty. Here we early-return upon empty completion queues, as well as full rx buffer, and save unnecessary logic and memory barriers.

2017-09-01mlxsw: spectrum_router: Set abort trap in all virtual routersIdo Schimmel1-3/+0
When the abort mechanism is invoked a default route directing packets to the CPU is programmed in all the virtual routers currently in use. This can result in packet loss in case a new VRF is configured. Upon abort, program the default route in all virtual routers, whether they are in use or not. The patch is directed at net-next since post-abort fixes aren't critical and packet loss due to a missing default route will be insignificant compared to packet loss caused by the CPU port policer.

2017-09-01mlxsw: spectrum: Forbid linking to devices that have uppersIdo Schimmel1-0/+6
The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.
