* net: sch: red: Change offloaded xstats to be incrementalNogah Frankel2018-01-102-19/+20
| | | | | | | | | | | | Change the value of the xstats requested from the driver for offloaded RED to be incremental, like the normal stats. It increases consistency - if a qdisc stops being offloaded its xstats don't change.

The penultimate patch in this set adds support for this new dynamic interrupt moderation library in the bnxt_en driver and the last patch creates an entry in the MAINTAINERS file for this library. The main purpose of this code is to allow an administrator to make sure that default coalesce settings are optimized for low latency, but quickly adapt to handle high throughput/bulk traffic by altering how much time passes before popping an interrupt. For any new driver the following changes would be needed to use this library: - add elements in ring struct to track items needed by this library - create function that can be called to actually set coalesce settings for the driver Credit to Rob Rice and Lee Reed for doing some of the initial proof of concept and testing for this patch and Tal Gilboa and Or Gerlitz for their comments, etc on this set. v4: Fix build breakage for VF representers noticed by kbuild test robot.

The first three patches convert multipath selection to use the hash-threshold method (RFC 2992) instead of modulo-N. The same method is employed by the IPv4 routing code since commit 0e884c78ee19 ("ipv4: L3 hash-based multipath"). Unlike modulo-N, with hash-threshold only the flows near the region boundaries are affected when a nexthop is added or removed. In addition, it allows us to easily add support for non-equal-cost multipath in the last patch by sizing the different regions according to the provided weights. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | The use of hash-threshold instead of modulo-N makes it trivial to add support for non-equal-cost multipath. Instead of dividing the multipath hash function's output space equally between the nexthops, each nexthop is assigned a region size which is proportional to its weight.

This reduces the number of checks we need to perform during lookup, as dead and linkdown nexthops are assigned a negative region boundary. In addition, in contrast to modulo-N, only flows near region boundaries are affected when a nexthop is added or removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | The hash thresholds assigned to IPv6 nexthops are in the range of [-1, 2^31 - 1], where a negative value is assigned to nexthops that should not be considered during multipath selection. Therefore, in a similar fashion to IPv4, we need to use the upper 31-bits of the multipath hash for multipath selection.

|/ | | | | | | | | | | | | | | | | Before we convert IPv6 to use hash-threshold instead of modulo-N, we first need each nexthop to store its region boundary in the hash function's output space. The boundary is calculated by dividing the output space equally between the different active nexthops. That is, nexthops that are not dead or linkdown. The boundaries are rebalanced whenever a nexthop is added or removed to a multipath route and whenever a nexthop becomes active or inactive.

* vhost_net: batch used ring update in rxJason Wang2018-01-101-4/+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.

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.

This commit changes the following: - Change parent ioctl function to be non static - Reuse the parent ioctl function in child devices Signed-off-by: Feras Daoud <ferasda@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
| * net/mlx5e: IPoIB, Use correct timestamp in child receive flowFeras Daoud2018-01-091-1/+6
| | | | | | | | | | | | | | | | | | | | The current implementation takes the child timestamp object from the parent since the rq in mlx5i_complete_rx_cqe belongs to the parent. This change fixes the issue by taking the correct timestamp.

| * net/mlx5e: Support offloading TC NIC hairpin flowsOr Gerlitz2018-01-092-12/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We refer to TC NIC rule that involves forwarding as "hairpin". All hairpin rules from the current NIC device (called "func" in the code) to a given NIC device ("peer") are steered into the same hairpin RQ/SQ pair. The hairpin pair is set on demand and removed when there are no TC rules that need it. Here's a TC rule that matches on icmp, does header re-write of the dst mac and hairpin from RX/enp1s2f1 to TX/enp1s2f2 (enp1s2f1/2 are two mlx5 devices): tc filter add dev enp1s2f1 protocol ip parent ffff: prio 2 flower skip_sw ip_proto icmp action pedit ex munge eth dst set 10:22:33:44:55:66 pipe action mirred egress redirect dev enp1s2f2 Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Emil fixes an issue with "wake on LAN"(WoL) where we need to ensure we enable the reception of multicast packets so that WoL works for IPv6 magic packets. Cleaned up code no longer needed with the update to adaptive ITR. Paul update the driver to advertise the highest capable link speed when a module gets inserted. Also extended the displaying of firmware version to include the iSCSI and OEM block in the EEPROM to better identify firmware versions/images. 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. Fixed up the MACVLAN limitations so we can now support 63 offloaded devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The l2 acceleration private pointer isn't needed in the ring struct. It isn't really used anywhere other than to test and see if we are supporting an offloaded macvlan netdev, and it is much easier to test netdev for not being ixgbe based to verify that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch simplifies the check for Tx pending traffic and makes it more holistic as there being any difference between next_to_use and next_to_clean is much more informative than if head and tail are equal, as it is possible for us to either not update tail, or not be notified of completed work in which case next_to_clean would not be equal to head. In addition the simplification makes it so that we don't have to read hardware which allows us to drop a number of variables that were previously being used in the call.

| * | ixgbe: Fix limitations on macvlan so we can support up to 63 offloaded devicesAlexander Duyck2018-01-094-43/+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.
