2017-10-21net: aquantia: Bad udp rate on default interrupt coalescingIgor Russkikh
Default Tx rates cause very long ISR delays on Tx. 0xff is 510us delay, giving only ~ 2000 interrupts per seconds for Tx rings cleanup. With these settings udp tx rate was never higher than ~800Mbps on a single stream. Changing min delay to 0xF makes it way better with ~6Gbps TCP stream performance is almost unaffected by this change, since LSO optimizations play important role. CPU load is affected insignificantly by this change. Signed-off-by: Pavel Belous <pavel.belous@aquantia.com> Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

2017-10-21net: aquantia: Enable coalescing management via ethtool interfaceIgor Russkikh
Aquantia NIC allows both TX and RX interrupt throttle rate (ITR) management, but this was used in a very limited way via predefined values. This patch allows to setup ITR default values via module command line arguments and via standard ethtool coalescing settings.

'net-sched-convert-cls-ndo_setup_tc-offload-calls-to-per-block-callbacks' Jiri Pirko says: ==================== net: sched: convert cls ndo_setup_tc offload calls to per-block callbacks This patchset is a bit bigger, but most of the patches are doing the same changes in multiple classifiers and drivers. I could do some squashes, but I think it is better split. This is another dependency on the way to shared block implementation. The goal is to remove use of tp->q in classifiers code. Also, this provides drivers possibility to track binding of blocks to qdiscs. Legacy drivers which do not support shared block offloading. register one callback per binding. That maintains the current functionality we have with ndo_setup_tc. Drivers which support block sharing offload register one callback per block which safes overhead. Patches 1-4 introduce the binding notifications and per-block callbacks Patches 5-8 add block callbacks calls to classifiers Patches 9-17 do convert from ndo_setup_tc calls to block callbacks for classifier offloads in drivers Patches 18-20 do cleanup v1->v2: - patch1: - move new enum value to the end ==================== Signed-off-by: David S.

My second patch adds missing OOM error handling in af_can. A patch by Stefan Mätje for the esd_usb2 driver fixes the dlc in received RTR frames.

The perf traces for ipv6 routing code show a relevant cost around trace_fib6_table_lookup(), even if no trace is enabled. This is due to the fib6_table de-referencing currently performed by the caller. Let's the tracing code pay this overhead, passing to the trace helper the table pointer.

2017-10-21net/ncsi: Enforce failover on link monitor timeoutGavin Shan
The NCSI channel has been configured to provide service if its link monitor timer is enabled, regardless of its state (inactive or active). So the timeout event on the link monitor indicates the out-of-service on that channel, for which a failover is needed. This sets NCSI_DEV_RESHUFFLE flag to enforce failover on link monitor timeout, regardless the channel's original state (inactive or active). Also, the link is put into "down" state to give the failing channel lowest priority when selecting for the active channel. The state of failing channel should be set to active in order for deinitialization and failover to be done.
