2017-03-14qed: Fix interrupt flags on Rx LL2Ram Amrani1-4/+5
Before iterating over the the LL2 Rx ring, the ring's spinlock is taken via spin_lock_irqsave(). The actual processing of the packet [including handling by the protocol driver] is done without said lock, so qed releases the spinlock and re-claims it afterwards. Problem is that the final spin_lock_irqrestore() at the end of the iteration uses the original flags saved from the initial irqsave() instead of the flags from the most recent irqsave(). So it's possible that the interrupt status would be incorrect at the end of the processing.

When deleting offloaded TC flows, we must correctly identify E-switch rules. The current check could get us wrong w.r.t to rules set on the PF. Since it's possible to set NIC rules on the PF, switch to SRIOV offloads mode and then attempt to delete a NIC rule. To solve that, we add a flags field to offloaded rules, set it on creation time and use that over the code where currently needed.

If the autogroups list wasn't empty and an empty group slot was found at the start of the list, the new group was added to the end of the list instead of the beginning, as the prev initializer was incorrect.

2017-03-09net: bcmgenet: Power up the internal PHY before probing the MIIDoug Berger1-0/+8
When using the internal PHY it must be powered up when the MII is probed or the PHY will not be detected. Since the PHY is powered up at reset this has not been a problem. However, when the kernel is restarted with kexec the PHY will likely be powered down when the kernel starts so it will not be detected and the Ethernet link will not be established. This commit explicitly powers up the internal PHY when the GENET driver is probed to correct this behavior.

2017-03-09net: thunderx: Fix IOMMU translation faultsSunil Goutham4-39/+156
ACPI support has been added to ARM IOMMU driver in 4.10 kernel and that has resulted in VNIC interfaces throwing translation faults when kernel is booted with ACPI as driver was not using DMA API. This patch fixes the issue by using DMA API which inturn will create translation tables when IOMMU is enabled. Also VNIC doesn't have a seperate receive buffer ring per receive queue, so there is no 1:1 descriptor index matching between CQE_RX and the index in buffer ring from where a buffer has been used for DMA'ing. Unlike other NICs, here it's not possible to maintain dma address to virt address mappings within the driver. This leaves us no other choice but to use IOMMU's IOVA address conversion API to get buffer's virtual address which can be given to network stack for processing.

2017-03-09liquidio: improve UDP TX performanceVSR Burru7-182/+144
Improve UDP TX performance by: * reducing the ring size from 2K to 512 * replacing the numerous streaming DMA allocations for info buffers and gather lists with one large consistent DMA allocation per ring BQL is not effective here. We reduced the ring size because there is heavy overhead with dma_map_single every so often. With iommu=on, dma_map_single in PF Tx data path was taking longer time (~700usec) for every ~250 packets. Debugged intel_iommu code, and found that PF driver is utilizing too many static IO virtual address mapping entries (for gather list entries and info buffers): about 100K entries for two PF's each using 8 rings. Also, finding an empty entry (in rbtree of device domain's iova mapping in kernel) during Tx path becomes a bottleneck every so often; the loop to find the empty entry goes through over 40K iterations; this is too costly and was the major overhead. Overhead is low when this loop quits quickly.

2017-03-07ibmvnic: Fix overflowing firmware/hardware TX queueThomas Falcon2-1/+27
Use a counter to track the number of outstanding transmissions sent that have not received completions. If the counter reaches the maximum number of queue entries, stop transmissions on that queue. As we receive more completions from firmware, wake the queue once the counter reaches an acceptable level. This patch prevents hardware/firmware TX queue from filling up and and generating errors. Since incorporating this fix, internal testing has reported that these firmware errors have stopped. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.
