2016-04-21net/mlx5e: Support RX multi-packet WQE (Striding RQ)Tariq Toukan
Introduce the feature of multi-packet WQE (RX Work Queue Element) referred to as (MPWQE or Striding RQ), in which WQEs are larger and serve multiple packets each. Every WQE consists of many strides of the same size, every received packet is aligned to a beginning of a stride and is written to consecutive strides within a WQE. In the regular approach, each regular WQE is big enough to be capable of serving one received packet of any size up to MTU or 64K in case of device LRO is enabled, making it very wasteful when dealing with small packets or device LRO is enabled. For its flexibility, MPWQE allows a better memory utilization (implying improvements in CPU utilization and packet rate) as packets consume strides according to their size, preserving the rest of the WQE to be available for other packets. MPWQE default configuration: Num of WQEs = 16 Strides Per WQE = 2048 Stride Size = 64 byte The default WQEs memory footprint went from 1024*mtu (~1.5MB) to 16 * 2048 * 64 = 2MB per ring. However, HW LRO can now be supported at no additional cost in memory footprint, and hence we turn it on by default and get an even better performance. Performance tested on ConnectX4-Lx 50G. To isolate the feature under test, the numbers below were measured with HW LRO turned off. We verified that the performance just improves when LRO is turned back on. * Netperf single TCP stream: - BW raised by 10-15% for representative packet sizes: default, 64B, 1024B, 1478B, 65536B. * Netperf multi TCP stream: - No degradation, line rate reached. * Pktgen: packet rate raised by 2-10% for traffic of different message sizes: 64B, 128B, 256B, 1024B, and 1500B. * Pktgen: packet loss in bursts of small messages (64byte), single stream: - | num packets | packets loss before | packets loss after | 2K | ~ 1K | 0 | 8K | ~ 6K | 0 | 16K | ~13K | 0 | 32K | ~28K | 0 | 64K | ~57K | ~24K As expected as the driver can receive as many small packets (<=64B) as the number of total strides in the ring (default = 2048 * 16) vs. 1024 (default ring size regardless of packets size) before this feature.

2016-04-20fm10k: do not disable PCI device in fm10k_io_error_detectedJacob Keller
fm10k_io_error_detected() does not need to call pci_disable_device(). In the cases where the reset needs to occur, the stack flow will result in calling fm10k_remove() which already disables the PCI device. If we leave the pci_disable_device(), we result in a warning about disabling an already disabled device. Many PCI drivers do call pci_disable_device() in their .error_detected() routines, but it does not appear to be required. In addition, these drivers have a check "is_pci_enabled()" call in their remove routines, which is how they chose to handle the duplicate device disable. This seems incorrect, since the PCI device structure is reference counted. It is very possible that the reference count for the PCI device could be greater than 1. In this case, you would remove the PCI device within the error_detected routine, reducing count to 1, then remove it again in the remove function, reducing it to zero. This would result in yet another disable somewhere else failing. Thus, we shouldn't be using is_pci_enabled() to check for this issue. Instead, just remove the extraneous pci_device_disable() found within the error_detected routine.

2016-04-20fm10k: correctly handle LPORT_MAP errorJacob Keller
Currently, any error responses from the switch manager after an LPORT_MAP request are silently ignored. At most the mailbox message will be reported as an error. This can result in unexpected behavior when the switch manager has configured a port with zero bandwidth. Add support for reading the fm10k_swapi_error structure from LPORT_MAP responses. If the message contains the necessary TLV and has a non-zero error code, report link down, clear the dglort_map, and delay the next get_host_state call by a reasonable delay. Also log an error message indicating that the LPORT_MAP request failed. The delay ensures preventing an interrupt storm on the switch manager, and reduces the number of mailbox messages we send in this scenario drastically.

2016-04-20fm10k: Fix multicast mode sync issuesNgai-Mint Kwan
Multicast mode checking is no longer a requirement to perform unicast and multicast address syncs. Specifically, a device operating in promiscuous and/or all multicast mode is not excluded. The issue occurs when the netdev is pre-configured to either multicast mode and is enabled for the first time. The multicast-group table in the Switch Manager will be missing obvious multicast entries associated to this netdev. Changes were also made to disallow unicast and multicast syncs with VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry. Requests with VLAN 0 by the netdev are only generated when the driver is freshly installed and the default VID is not set.

2016-04-20fm10k: add helper functions to set strings and data for ethtool statsJacob Keller
Reduce duplicate code and the amount of indentation by adding fm10k_add_stat_strings and fm10k_add_ethtool_stats functions which help add fm10k_stat structures to the ethtool stats callbacks. This helps increase ease of use for future stat additions, and increases code readability.

2016-04-20ath10k: refactor firmware images to struct ath10k_fw_componentsKalle Valo
To make it easier to share ath10k_core_fetch_board_data_api_n() with testmode.c refactor all firmware components to struct ath10k_fw_components. This structure will hold firmware related files, for example firmware-N.bin and board-N.bin. For firmware-N.bin create a new struct ath10k_fw_file which contains the actual firmware image as well as the parsed data from the image. Modify ath10k_core_start() to take struct ath10k_fw_components() as an argument which makes it possible in following patches to drop some ugly hacks from testmode.c.
