2018-01-10mlxsw: spectrum: qdiscs: Create a generic replace functionNogah Frankel1-38/+71
Create a generic qdisc replace function. For that goal, add three functions to the qdisc ops struct: * check_params: Checks if the given parameters are offloadable. * replace: Offload the given parameters. * clean_stats: clean the qdisc stats for the offloaded qdisc. integrate RED offloading into using the new internal replace API.

2018-01-10mlxsw: spectrum: qdiscs: Unite all handle checksNogah Frankel1-21/+22
Every qdisc op gets the qdisc handle ID as well as its location. Each one of them, beside replace, checks if the handle doesn't match the qdisc in the given location, and if so, it returns without running the actual op. Unite these checks to one comparison function and avoid sending the handle id to these ops.

2018-01-10vhost_net: batch used ring update in rxJason Wang1-4/+11
This patch tries to batched used ring update during RX. This is pretty fit for the case when guest is much faster (e.g dpdk based backend). In this case, used ring is almost empty: - we may get serious cache line misses/contending on both used ring and used idx. - at most 1 packet could be dequeued at one time, batching in guest does not make much effect. Update used ring in a batch can help since guest won't access the used ring until used idx was advanced for several descriptors and since we advance used ring for every N packets, guest will only need to access used idx for every N packet since it can cache the used idx. To have a better interaction for both batch dequeuing and dpdk batching, VHOST_RX_BATCH was used as the maximum number of descriptors that could be batched. Test were done between two machines with 2.40GHz Intel(R) Xeon(R) CPU E5-2630 connected back to back through ixgbe. Traffic were generated on one remote ixgbe through MoonGen and measure the RX pps through testpmd in guest when do xdp_redirect_map from local ixgbe to tap. RX pps were increased from 3.05 Mpps to 4.00 Mpps (about 31% improvement). One possible concern for this is the implications for TCP (especially latency sensitive workload). Result[1] does not show obvious changes for most of the netperf test (RR, TX, and RX). And we do get some improvements for RX on some specific size.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2018-01-08 Four patches from Or that add Hairpin support to mlx5: =========================================================== From: Or Gerlitz <ogerlitz@mellanox.com> We refer the ability of NIC HW to fwd packet received on one port to the other port (also from a port to itself) as hairpin. The application API is based on ingress tc/flower rules set on the NIC with the mirred redirect action. Other actions can apply to packets during the redirect. Hairpin allows to offload the data-path of various SW DDoS gateways, load-balancers, etc to HW. Packets go through all the required processing in HW (header re-write, encap/decap, push/pop vlan) and then forwarded, CPU stays at practically zero usage. HW Flow counters are used by the control plane for monitoring and accounting. Hairpin is implemented by pairing a receive queue (RQ) to send queue (SQ). All the flows that share <recv NIC, mirred NIC> are redirected through the same hairpin pair. Currently, only header-rewrite is supported as a packet modification action. I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing this functionality on HW simulator, before it was avail in the FW so the driver code could be tested early. =========================================================== From Feras three patches that provide very small changes that allow IPoIB to support RX timestamping for child interfaces, simply by hooking the mlx5e timestamping PTP ioctl to IPoIB child interface netdev profile. One patch from Gal to fix a spilling mistake. Two patches from Eugenia adds drop counters to VF statistics to be reported as part of VF statistics in netlink (iproute2) and implemented them in mlx5 eswitch. Signed-off-by: David S.

Tonghao Zhang cleans up a code comment that no longer applies since InterruptThrottleRate has been removed from the driver. Alex fixes SR-IOV and MACVLAN offload interaction, where the MACVLAN offload was incorrectly configuring several filters with the wrong pool value which resulted in MACLVAN interfaces not being able to receive traffic that had to pass over the physical interface. Fixed transmit hangs and dropped receive frames when the number of VFs changed. Added support for RSS on MACVLAN pools for X550 devices.

2018-01-09r8169: improve runtime pm in general and suspend unused portsHeiner Kallweit1-8/+12
So far rpm doesn't cover cases like unused ports which are never brought up. If they are active at probe time they remain in this state. Included in this patch: - Let the idle notification check whether we can suspend and let it schedule the suspend. This way we don't need to have calls to pm_schedule_suspend in different places. - At the end of rtl_open and rtl_init_one send an idle notification to allow suspending if the link is down. If a cable is plugged in aneg is finished before the suspend timer expires and the suspend request is cancelled. - Change rtl8169_runtime_suspend to power down the chip if the interface is down.

This patch partially reverts commit e4fbce740f07 "r8169: Fix runtime power management" from 2010. At that time the suspend delay was 100ms and therefore suspending happened during initial aneg. Currently suspend delay is 5s, so suspend starts after aneg and the issue doesn't exist any longer. On my system aneg takes almost 3s, to be on the safe side let's increase the suspend delay to 10s.

2018-01-09ixgbe: Fix limitations on macvlan so we can support up to 63 offloaded devicesAlexander Duyck4-43/+34
This change is a fix of the macvlan offload so that we correctly handle macvlan offloaded devices. Specifically we were configuring our limits based on the assumption that we were going to max out the RSS indices for every mode. As a result when we went to 15 or more macvlan interfaces we were forced into the 2 queue RSS mode on VFs even though they could have still supported 4. This change splits the logic up so that we limit either the total number of macvlan instances if DCB is enabled, or limit the number of RSS queues used per macvlan (instead of per pool) if SR-IOV is enabled. By doing this we can make best use of the part. In addition I have increased the maximum number of supported interfaces to 63 with one queue per offloaded interface as this more closely reflects the actual values supported by the interface.

The num_rx_pools value is overwritten when we reinitialize the queue configuration. In reality we shouldn't need to be updating the value since it is redone every time we call into ixgbe_setup_tc so for now just drop the spots where we were incrementing or decrementing the value.

2018-01-09ixgbe: Add support for macvlan offload RSS on X550 and clean-up pool handlingAlexander Duyck1-37/+25
In order for RSS to work on the macvlan pools of the X550 we need to populate the MRQC, RETA, and RSS key values for each pool. This patch makes it so that we now take care of that. In addition I have dropped the macvlan specific configuration of psrtype since it is redundant with the code that already exists for configuring this value.

2018-01-09ixgbe: Perform reinit any time number of VFs changeAlexander Duyck1-16/+3
If the number of VFs are changed we need to reinitialize the part since the offset for the device and the number of pools will be incorrect. Without this change we can end up seeing Tx hangs and dropped Rx frames for incoming traffic. In addition we should drop the code that is arbitrarily changing the default pool and queue configuration. Instead we should wait until the port is reset and reconfigured via ixgbe_sriov_reinit.

2018-01-09ixgbe: Fix interaction between SR-IOV and macvlan offloadAlexander Duyck1-7/+5
When SR-IOV was enabled the macvlan offload was configuring several filters with the wrong pool value. This would result in the macvlan interfaces not being able to receive traffic that had to pass over the physical interface. To fix it wrap the pool argument in the VMDQ_P macro which will add the necessary offset to get to the actual VMDq pool Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2018-01-09virtio_net: propagate linkspeed/duplex settings from the hypervisorJason Baron1-1/+22
The ability to set speed and duplex for virtio_net is useful in various scenarios as described here: 16032be virtio_net: add ethtool support for set and get of settings However, it would be nice to be able to set this from the hypervisor, such that virtio_net doesn't require custom guest ethtool commands. Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows the hypervisor to export a linkspeed and duplex setting. The user can subsequently overwrite it later if desired via: 'ethtool -s'. Note that VIRTIO_NET_F_SPEED_DUPLEX is defined as bit 63, the intention is that device feature bits are to grow down from bit 63, since the transports are starting from bit 24 and growing up.
