'tcp_bbr-Improving-TCP-BBR-performance-for-WiFi-and-cellular-networks' Priyaranjan Jha says: ==================== tcp_bbr: Improving TCP BBR performance for WiFi and cellular networks Ack aggregation is quite prevalent with wifi, cellular and cable modem link tchnologies, ACK decimation in middleboxes, and common offloading techniques such as TSO and GRO, at end hosts. Previously, BBR was often cwnd-limited in the presence of severe ACK aggregation, which resulted in low throughput due to insufficient data in flight. To achieve good throughput for wifi and other paths with aggregation, this patch series implements an ACK aggregation estimator for BBR, which estimates the maximum recent degree of ACK aggregation and adapts cwnd based on it. The algorithm is further described by the following presentation: https://datatracker.ietf.org/meeting/101/materials/slides-101-iccrg-an-update-on-bbr-work-at-google-00 (1) A preparatory patch, which refactors bbr_target_cwnd for generic inflight provisioning.

2019-01-24tcp_bbr: adapt cwnd based on ack aggregation estimationPriyaranjan Jha
Aggregation effects are extremely common with wifi, cellular, and cable modem link technologies, ACK decimation in middleboxes, and LRO and GRO in receiving hosts. The aggregation can happen in either direction, data or ACKs, but in either case the aggregation effect is visible to the sender in the ACK stream. Previously BBR's sending was often limited by cwnd under severe ACK aggregation/decimation because BBR sized the cwnd at 2*BDP. If packets were acked in bursts after long delays (e.g. one ACK acking 5*BDP after 5*RTT), BBR's sending was halted after sending 2*BDP over 2*RTT, leaving the bottleneck idle for potentially long periods. Note that loss-based congestion control does not have this issue because when facing aggregation it continues increasing cwnd after bursts of ACKs, growing cwnd until the buffer is full. To achieve good throughput in the presence of aggregation effects, this algorithm allows the BBR sender to put extra data in flight to keep the bottleneck utilized during silences in the ACK stream that it has evidence to suggest were caused by aggregation. A summary of the algorithm: when a burst of packets are acked by a stretched ACK or a burst of ACKs or both, BBR first estimates the expected amount of data that should have been acked, based on its estimated bandwidth. Then the surplus ("extra_acked") is recorded in a windowed-max filter to estimate the recent level of observed ACK aggregation. Then cwnd is increased by the ACK aggregation estimate. The larger cwnd avoids BBR being cwnd-limited in the face of ACK silences that recent history suggests were caused by aggregation. As a sanity check, the ACK aggregation degree is upper-bounded by the cwnd (at the time of measurement) and a global max of BW * 100ms. The algorithm is further described by the following presentation: https://datatracker.ietf.org/meeting/101/materials/slides-101-iccrg-an-update-on-bbr-work-at-google-00 In our internal testing, we observed a significant increase in BBR throughput (measured using netperf), in a basic wifi setup. - Host1 (sender on ethernet) -> AP -> Host2 (receiver on wifi) - 2.4 GHz -> BBR before: ~73 Mbps; BBR after: ~102 Mbps; CUBIC: ~100 Mbps - 5.0 GHz -> BBR before: ~362 Mbps; BBR after: ~593 Mbps; CUBIC: ~601 Mbps Also, this code is running globally on YouTube TCP connections and produced significant bandwidth increases for YouTube traffic. This is based on Ian Swett's max_ack_height_ algorithm from the QUIC BBR implementation.

Also the state machine should be started only when being called from one of the valid states. Some more background: For all invalid states phy_start() basically was a no-op. All it did was triggering a state machine run, but for all "running" states the poll loop was active anyway.

2019-01-24enetc: Add RFS and RSS supportClaudiu Manoil
A ternary match table is used for RFS. If multiple entries in the table match, the entry with the lowest numerical values index is chosen as the matching entry. Entries in the table are identified using an index which takes a value from 0 to PRFSCAPR[NUM_RFS]-1 when accessed by the PSI (PF). Portions of the RFS table can be assigned to each SI by the PSI (PF) driver in PSIaRFSCFGR. Assignments are cumulative, the entries assigned to SIn start after those assigned to SIn-1. The total assignments to all SIs must be equal to or less than the number available to the port as found in PRFSCAPR. For RSS, the Toeplitz hash function used requires two inputs, a 40B random secret key that is supplied through the PRSSKR0-9 registers as well as the relevant pieces of the packet header (n-tuple). The 6 LSB bits of the hash function result will then be used as a pointer to obtain the tag referenced in the 64 entry indirection table. The result will provide a winning group which will be used to help route the received packet.

2019-01-24enetc: Introduce basic PF and VF ENETC ethernet driversClaudiu Manoil
ENETC is a multi-port virtualized Ethernet controller supporting GbE designs and Time-Sensitive Networking (TSN) functionality. ENETC is operating as an SR-IOV multi-PF capable Root Complex Integrated Endpoint (RCIE). As such, it contains multiple physical (PF) and virtual (VF) PCIe functions, discoverable by standard PCI Express. Introduce basic PF and VF ENETC ethernet drivers. The PF has access to the ENETC Port registers and resources and makes the required privileged configurations for the underlying VF devices. Common functionality is controlled through so called System Interface (SI) register blocks, PFs and VFs own a SI each. Though SI register blocks are almost identical, there are a few privileged SI level controls that are accessible only to PFs, and so the distinction is made between PF SIs (PSI) and VF SIs (VSI). As such, the bulk of the code, including datapath processing, basic h/w offload support and generic pci related configuration, is shared between the 2 drivers and is factored out in common source files (i.e. enetc.c). Major functionalities included (for both drivers): MSI-X support for Rx and Tx processing, assignment of Rx/Tx BD ring pairs to MSI-X entries, multi-queue support, Rx S/G (Rx frame fragmentation) and jumbo frame (up to 9600B) support, Rx paged allocation and reuse, Tx S/G support (NETIF_F_SG), Rx and Tx checksum offload, PF MAC filtering and initial control ring support, VLAN extraction/ insertion, PF Rx VLAN CTAG filtering, VF mac address config support, VF VLAN isolation support, etc. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: David S.

This patch fixes the following warning: drivers/net/ethernet/mellanox/mlx4/eq.c: In function ‘mlx4_eq_int’: drivers/net/ethernet/mellanox/mlx4/mlx4.h:219:5: warning: this statement may fall through [-Wimplicit-fallthrough=] if (mlx4_debug_level) \ ^ drivers/net/ethernet/mellanox/mlx4/eq.c:558:4: note: in expansion of macro ‘mlx4_dbg’ mlx4_dbg(dev, "%s: MLX4_EVENT_TYPE_SRQ_LIMIT. srq_no=0x%x, eq 0x%x\n", ^~~~~~~~ drivers/net/ethernet/mellanox/mlx4/eq.c:561:3: note: here case MLX4_EVENT_TYPE_SRQ_CATAS_ERROR: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.

2019-01-22devlink: Use DIV_ROUND_UP_ULL in DEVLINK_HEALTH_SIZE_TO_BUFFERSNathan Chancellor
When building this code on a 32-bit platform such as ARM, there is a link time error (lld error shown, happpens with ld.bfd too): ld.lld: error: undefined symbol: __aeabi_uldivmod >>> referenced by devlink.c >>> net/core/devlink.o:(devlink_health_buffers_create) in archive built-in.a This happens when using a regular division symbol with a u64 dividend. Use DIV_ROUND_UP_ULL, which wraps do_div, to avoid this situation.
