2019-10-28net: ethernet: ftgmac100: Fix DMA coherency issue with SW checksumBenjamin Herrenschmidt
We are calling the checksum helper after the dma_map_single() call to map the packet. This is incorrect as the checksumming code will touch the packet from the CPU. This means the cache won't be properly flushes (or the bounce buffering will leave us with the unmodified packet to DMA). This moves the calculation of the checksum & vlan tags to before the DMA mapping. This also has the side effect of fixing another bug: If the checksum helper fails, we goto "drop" to drop the packet, which will not unmap the DMA mapping.

When receiving traffic, eth_type_trans() is high up on the perf top list, because it's the first function which access the packet data. Move the DMA unmap a bit higher, and put a prefetch just after it, so we have more time to load the data into the cache.

Even out Rx performance across MTU sizes by changing from full skb allocations to page-based frag allocations. The device supports a form of scatter-gather in the Rx path, so we can set up a number of pages for each descriptor, all of which are easier to alloc and pass around than the standard kzalloc'd buffer. An skb is wrapped around the pages while processing the received packets, and pages are recycled as needed, or left alone if they weren't used in the Rx.

2019-10-25cxgb4: request the TX CIDX updates to status pageRaju Rangoju
For adapters which support the SGE Doorbell Queue Timer facility, we configured the Ethernet TX Queues to send CIDX Updates to the Associated Ethernet RX Response Queue with CPL_SGE_EGR_UPDATE messages to allow us to respond more quickly to the CIDX Updates. But, this was adding load to PCIe Link RX bandwidth and, potentially, resulting in higher CPU Interrupt load. This patch requests the HW to deliver the CIDX updates to the TX queue status page rather than generating an ingress queue message (as an interrupt). With this patch, the load on RX bandwidth is reduced and a substantial improvement in BW is noticed at lower IO sizes.

2019-10-25i40e: Refactoring VF MAC filters counting to make more reliableAleksandr Loktionov
This patch prepares ground for the next VF MAC address change fix. It lets untrusted VF to delete any VF mac filter, but it still doesn't let untrusted VF to add mac filter not setup by PF. It removes information duplication in num_mac mac filters counter. And improves exact h/w mac filters usage checking in the i40e_check_vf_permission() function by counting mac2add_cnt. It also improves logging because now all mac addresses will be validated first and corresponding messages will be logged.

2019-10-25i40e: initialize ITRN registers with correct valuesNicholas Nunley
Since commit 92418fb14750 ("i40e/i40evf: Use usec value instead of reg value for ITR defines") the driver tracks the interrupt throttling intervals in single usec units, although the actual ITRN/ITR0 registers are programmed in 2 usec units. Most register programming flows in the driver correctly handle the conversion, although it is currently not applied when the registers are initialized to their default values. Most of the time this doesn't present a problem since the default values are usually immediately overwritten through the standard adaptive throttling mechanism, or updated manually by the user, but if adaptive throttling is disabled and the interval values are left alone then the incorrect value will persist. Since the intended default interval of 50 usecs (vs. 100 usecs as programmed) performs better for most traffic workloads, this can lead to performance regressions. This patch adds the correct conversion when writing the initial values to the ITRN registers.

2019-10-25i40e: Extend PHY access with page change flagPiotr Azarewicz
Currently FW use MDIO I/F number corresponded with current PF for PHY access. This code allow to specify used MDIO I/F number. Add new field - command flags with only one flag for now. Added flag tells FW that it shouldn't change page while accessing QSFP module, as it was set manually.

2019-10-25iwlwifi: dbg_ini: use vzalloc to allocate dumping memory regionsShahar S Matityahu
During dump flow, the driver allocates spaces to store the memory regions that will be included in the dump. These regions can be very large so in order to avoid allocation failure, use vzalloc instead. The kmalloc uses GFP_KERNEL and the driver does not make any use of the fact that the memory is contiguous so the same functionality is maintained.
