This move allows drivers to add private structure elements to track the number of packets, bytes, and interrupts events per ring. A driver also defines a workqueue handler to act on this collected data once per poll and modify the coalescing parameters per ring.

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.

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 e4fbce74 "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.

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.

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.

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.

The ability to set speed and duplex for virtio_net is useful in various scenarios as described here: 16032be5 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.

This patch implements XDP transmission for TAP. Since we can't create new queues for TAP during XDP set, exist ptr_ring was reused for queuing XDP buffers. To differ xdp_buff from sk_buff, TUN_XDP_FLAG (0x1UL) was encoded into lowest bit of xpd_buff pointer during ptr_ring_produce, and was decoded during consuming. XDP metadata was stored in the headroom of the packet which should work in most of cases since driver usually reserve enough headroom. Very minor changes were done for vhost_net: it just need to peek the length depends on the type of pointer. Tests were done on two Intel E5-2630 2.40GHz machines connected back to back through two 82599ES. Traffic were generated/received through MoonGen/testpmd(rxonly).
