2015-08-10wl18xx: use long intervals in sched scanEliad Peller5-6/+34
Add support for long intervals on sched scan. If configured, the original request interval will be used num_short_interval times, and then the long interval will be used. While on it, fix the scan command field names to reflect the expected value is in ms (rather than secs). These values will be taken from the conf file, so bump its version accordingly.

This patch changes the state change behaviour of at86rf230 to always TX_ARET mode. According the at86rf2xx datasheets TX_ARET mode doesn't mean to be always waiting for ack frames after transmit. The transceiver will automatically wait for ack frames or not if the acknowledge request bit is set. See section "TX_ARET_ON – Transmit with Automatic Frame Retransmission and CSMA-CA Retry".

2015-08-10bna: fix interrupts storm caused by erroneous packetsIvan Vecera1-1/+1
The commit "e29aa33 bna: Enable Multi Buffer RX" moved packets counter increment from the beginning of the NAPI processing loop after the check for erroneous packets so they are never accounted. This counter is used to inform firmware about number of processed completions (packets). As these packets are never acked the firmware fires IRQs for them again and again.

2015-08-10net: mvpp2: replace TX coalescing interrupts with hrtimerMarcin Wojtas1-47/+130
The PP2 controller is capable of per-CPU TX processing, which means there are per-CPU banked register sets and queues. Current version of the driver supports TX packet coalescing - once on given CPU sent packets amount reaches a threshold value, an IRQ occurs. However, there is a single interrupt line responsible for CPU0/1 TX and RX events (the latter is not per-CPU, the hardware does not support RSS). When the top-half executes the interrupt cause is not known. This is why in NAPI poll function, along with RX processing, IRQ cause register on both CPU's is accessed in order to determine on which of them the TX coalescing threshold might have been reached. Thus the egress processing and releasing the buffers is able to take place on the corresponding CPU. Hitherto approach lead to an illegal usage of on_each_cpu function in softirq context. The problem is solved by resigning from TX coalescing interrupts and separating egress finalization from NAPI processing. For that purpose a method of using hrtimer is introduced. In main transmit function (mvpp2_tx) buffers are released once a software coalescing threshold is reached. In case not all the data is processed a timer is set on this CPU - in its interrupt context a tasklet is scheduled in which all queues are processed. At once only one timer per-CPU can be running, which is controlled by a dedicated flag. This commit removes TX processing from NAPI polling function, disables hardware coalescing and enables hrtimer with tasklet, using new per-CPU port structure (mvpp2_port_pcpu).

2015-08-10net: mvpp2: enable proper per-CPU TX buffers unmappingMarcin Wojtas1-15/+37
mvpp2 driver allows usage of per-CPU TX processing. Once the packets are prepared independetly on each CPU, the hardware enqueues the descriptors in common TX queue. After they are sent, the buffers and associated sk_buffs should be released on the corresponding CPU. This is why a special index is maintained in order to point to the right data to be released after transmission takes place. Each per-CPU TX queue comprise an array of sent sk_buffs, freed in mvpp2_txq_bufs_free function. However, the index was used there also for obtaining a descriptor (and therefore a buffer to be DMA-unmapped) from common TX queue, which was wrong, because it was not referring to the current CPU. This commit enables proper unmapping of sent data buffers by indexing them in per-CPU queues using a dedicated array for keeping their physical addresses.

2015-08-09NTB: Fix ntb_transport out-of-order RX updateAllen Hubbe1-0/+7
It was possible for a synchronous update of the RX index in the error case to get ahead of the asynchronous RX index update in the normal case. Change the RX processing to preserve an RX completion order. There were two error cases. First, if a buffer is not present to receive data, there would be no queue entry to preserve the RX completion order. Instead of dropping the RX frame, leave the RX frame in the ring. Schedule RX processing when RX entries are enqueued, in case there are RX frames waiting in the ring to be received. Second, if a buffer is too small to receive data, drop the frame in the ring, mark the RX entry as done, and indicate the error in the RX entry length. Check for a negative length in the receive callback in ntb_netdev, and count occurrences as rx_length_errors.

2015-08-07net/mlx5e: Light-weight netdev open/stopAchiad Shochat3-75/+176
Create/destroy TIRs, TISs and flow tables upon PCI probe/remove rather than upon the netdev ndo_open/stop. Upon ndo_stop(), redirect all RX traffic to the (lately introduced) "Drop RQ" and then close only the RX/TX rings, leaving the TIRs, TISs and flow tables alive.

2015-08-07net/mlx5e: Introduce the "Drop RQ"Achiad Shochat2-11/+114
RX traffic routed to this RQ will be silently dropped, at the NIC HW level. This is in preparation for netdev "light-weight" open/stop flow change described in previous commit.

2015-08-07net/mlx5e: Unify the RX flowAchiad Shochat2-34/+69
Generally an RX packet flows through the following objects: Flow table --> TIR --> RQT --> RQ Where: - TIR stands for "Transport Interface Receive", defining the RSS and LRO paramaters. - RQT stands for "RQ Table", implementing the RSS indirection table. - RQ stands for "Receive Queue" For flows that do not need LRO, nor RSS, the driver made a shortcut to the above RX flow by pointing to the RQ directly from the TIR, yielding this flow: Flow table --> TIR --> RQ In this commit we remove this shortcut by "inserting" a single-RQ RQT between the TIR and the RQ, i.e RX packets will reach the same RQ but will go through an RQT of size 1, pointing to just a single RQ. This way the RX traffic re-direction to/from the "Drop RQ" will be more uniform (AKA "one flow"), as it will involve only RQTs re-direction and no TIRs re-direction.

2015-08-07drivers: net: cpsw: add separate napi for txMugunthan V N1-13/+31
Instead of processing tx events in isr adding separate napi for tx which improves performance by ~180Mbps with omap2plus_defconfig on DRA74x platform. Also cleaning up rx napis by renaming to napi_rx for better understanding the code. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-07drivers: net: cpsw: dual_emac: simplify napi usageMugunthan V N1-17/+9
Since interrupt is shared between the two ethernet interface and in isr only one napi is scheduled at an instance so having two napis doesn't make any difference. So making napi also as a common resource for the dual ethernet interfaces. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: David S. Miller <davem@davemloft.net>
