Similar to MTK Wireless Ethernet Dispatcher (WED) MCU rx queue, we do not need to protect WED MCU tx queue with a spin lock since the tx queue is accessed in the two following routines: - mtk_wed_wo_queue_tx_skb(): it is run at initialization and during mt7915 normal operation. Moreover MCU messages are serialized through MCU mutex. - mtk_wed_wo_queue_tx_clean(): it runs just at mt7915 driver module unload when no more messages are sent to the MCU. Remove tx queue spinlock.

In ip6_dst_gc() replace: if (entries > gc_thresh) With: if (entries > ops->gc_thresh) Sending Ipv6 packets in a loop via a raw socket triggers an issue where a route is cloned by ip6_rt_cache_alloc() for each packet sent. This quickly consumes the Ipv6 max_size threshold which defaults to 4096 resulting in these warnings: [1] 99.187805] dst_alloc: 7728 callbacks suppressed [2] Route cache is full: consider increasing sysctl net.ipv6.route.max_size. . .

Add 2 tracepoints to monitor the tcp/udp traffic of per process and per cgroup. Regarding monitoring the tcp/udp traffic of each process, there are two existing solutions, the first one is https://www.atoptool.nl/netatop.php. The second is via kprobe/kretprobe. Netatop solution is implemented by registering the hook function at the hook point provided by the netfilter framework. These hook functions may be in the soft interrupt context and cannot directly obtain the pid. Some data structures are added to bind packets and processes. For example, struct taskinfobucket, struct taskinfo ... Every time the process sends and receives packets it needs multiple hashmaps,resulting in low performance and it has the problem fo inaccurate tcp/udp traffic statistics(for example: multiple threads share sockets). We can obtain the information with kretprobe, but as we know, kprobe gets the result by trappig in an exception, which loses performance compared to tracepoint. We compared the performance of tracepoints with the above two methods, and the results are as follows: ab -n 1000000 -c 1000 -r http://127.0.0.1/index.html without trace: Time per request: 39.660 [ms] (mean) Time per request: 0.040 [ms] (mean, across all concurrent requests) netatop: Time per request: 50.717 [ms] (mean) Time per request: 0.051 [ms] (mean, across all concurrent requests) kr: Time per request: 43.168 [ms] (mean) Time per request: 0.043 [ms] (mean, across all concurrent requests) tracepoint: Time per request: 41.004 [ms] (mean) Time per request: 0.041 [ms] (mean, across all concurrent requests It can be seen that tracepoint has better performance.

Daniele Palmas says: ==================== net: add tx packets aggregation to ethtool and rmnet Hello maintainers and all, this patchset implements tx qmap packets aggregation in rmnet and generic ethtool support for that. Some low-cat Thread-x based modems are not capable of properly reaching the maximum allowed throughput both in tx and rx during a bidirectional test if tx packets aggregation is not enabled. I verified this problem with rmnet + qmi_wwan by using a MDM9207 Cat. 4 based modem (50Mbps/150Mbps max throughput). What is actually happening is pictured at https://drive.google.com/file/d/1gSbozrtd9h0X63i6vdkNpN68d-9sg8f9/view Testing with iperf TCP, when rx and tx flows are tested singularly there's no issue in tx and minor issues in rx (not able to reach max throughput). When there are concurrent tx and rx flows, tx throughput has an huge drop. rx a minor one, but still present. The same scenario with tx aggregation enabled is pictured at https://drive.google.com/file/d/1jcVIKNZD7K3lHtwKE5W02mpaloudYYih/view showing a regular graph. This issue does not happen with high-cat modems (e.g. SDX20), or at least it does not happen at the throughputs I'm able to test currently: maybe the same could happen when moving close to the maximum rates supported by those modems. Anyway, having the tx aggregation enabled should not hurt. The first attempt to solve this issue was in qmi_wwan qmap implementation, see the discussion at https://lore.kernel.org/netdev/20221019132503.6783-1-dnlplm@gmail.com/ However, it turned out that rmnet was a better candidate for the implementation. Moreover, Greg and Jakub suggested also to use ethtool for the configuration: not sure if I got their advice right, but this patchset add also generic ethtool support for tx aggregation. The patches have been tested mainly against an MDM9207 based modem through USB and SDX55 through PCI (MHI). v2 should address the comments highlighted in the review: the implementation is still in rmnet, due to Subash's request of keeping tx aggregation there. v3 fixes ethtool-netlink.rst content out of table bounds and a W=1 build warning for patch 2. v4 solves a race related to egress_agg_params. ==================== Signed-off-by:

Add tx packets aggregation. Bidirectional TCP throughput tests through iperf with low-cat Thread-x based modems revelead performance issues both in tx and rx. The Windows driver does not show this issue: inspecting USB packets revealed that the only notable change is the driver enabling tx packets aggregation. Tx packets aggregation is by default disabled and can be enabled by increasing the value of ETHTOOL_A_COALESCE_TX_MAX_AGGR_FRAMES. The maximum aggregated size is by default set to a reasonably low value in order to support the majority of modems.

Arun Ramadoss says: ==================== net: dsa: microchip: add PTP support for KSZ9563/KSZ8563 and LAN937x KSZ9563/KSZ8563 and LAN937x switch are capable for supporting IEEE 1588 PTP protocol. LAN937x has the same PTP register set similar to KSZ9563, hence the implementation has been made common for the KSZ switches. KSZ9563 does not support two step timestamping but LAN937x supports both. Tested the 1step & 2step p2p timestamping in LAN937x and p2p1step timestamping in KSZ9563. This patch series is based on the Christian Eggers PTP support for KSZ9563. Applied the Christian patch and updated as per the latest refactoring of KSZ series code. The features added on top are PTP packet Interrupt implementation based on nested handler, LAN937x two step timestamping and programmable per_out pins.

There is difference in implementation of per_out pins between KSZ9563 and LAN937x. In KSZ9563, Timestamping control register (0x052C) bit 6, if 1 - timestamp input and 0 - trigger output. But it is opposite for LAN937x 1 - trigger output and 0 - timestamp input. As per per_out gpio pins, KSZ9563 has four Led pins and two dedicated gpio pins. But in LAN937x dedicated gpio pins are removed instead there are up to 10 LED pins out of which LED_0 and LED_1 can be mapped to PTP tou 0, 1 or 2. This patch sets the bit 6 in 0x052C register and configure the LED override and source register for LAN937x series of switches alone. Signed-off-by:

LAN937x series of switches support 2 step timestamping mechanism. There are timestamp correction calculation performed in ksz_rcv_timestamp and ksz_xmit_timestamp which are applicable only for p2p1step. To check whether the 2 step is enabled or not in tag_ksz.c introduced the helper function in taggger_data to query it from ksz_ptp.c. Based on whether 2 step is enabled or not, timestamp calculation are performed. Signed-off-by:

For PDelay_Resp messages we will likely have a negative value in the correction field. The switch hardware cannot correctly update such values (produces an off by one error in the UDP checksum), so it must be moved to the time stamp field in the tail tag. Format of the correction field is 48 bit ns + 16 bit fractional ns. After updating the correction field, clone is no longer required hence it is freed. Signed-off-by:

This patch adds the routines for transmission of ptp packets. When the ptp pdelay_req packet to be transmitted, it uses the deferred xmit worker to schedule the packets. During irq_setup, interrupt for Sync, Pdelay_req and Pdelay_rsp are enabled. So interrupt is triggered for all three packets. But for p2p1step, we require only time stamp of Pdelay_req packet. Hence to avoid posting of the completion from ISR routine for Sync and Pdelay_resp packets, ts_en flag is introduced. This controls which packets need to processed for timestamp. After the packet is transmitted, ISR is triggered. The time at which packet transmitted is recorded to separate register. This value is reconstructed to absolute time and posted to the user application through socket error queue. Signed-off-by:

Rx Timestamping is done through 4 additional bytes in tail tag. Whenever the ptp packet is received, the 4 byte hardware time stamped value is added before 1 byte tail tag. Also, bit 7 in tail tag indicates it as PTP frame. This 4 byte value is extracted from the tail tag and reconstructed to absolute time and assigned to skb hwtstamp. If the packet received in PDelay_Resp, then partial ingress timestamp is subtracted from the correction field. Since user space tools expects to be done in hardware. Signed-off-by:

For P2P delay measurement, the ingress time stamp of the PDelay_Req is required for the correction field of the PDelay_Resp. The application echoes back the correction field of the PDelay_Req when sending the PDelay_Resp. Some hardware (like the ZHAW InES PTP time stamping IP core) subtracts the ingress timestamp autonomously from the correction field, so that the hardware only needs to add the egress timestamp on tx. Other hardware (like the Microchip KSZ9563) reports the ingress time stamp via an interrupt and requires that the software provides this time stamp via tail-tag on tx. In order to avoid introducing a further application interface for this, the driver can simply emulate the behavior of the InES device and subtract the ingress time stamp in software from the correction field. On egress, the correction field can either be kept as it is (and the time stamp field in the tail-tag is set to zero) or move the value from the correction field back to the tail-tag. Changing the correction field requires updating the UDP checksum (if UDP is used as transport). Signed-off-by:

PTP Interrupt mask and status register differ from the global and port interrupt mechanism by two methods. One is that for global/port interrupt enabling we have to clear the bit but for ptp interrupt we have to set the bit. And other is bit12:0 is reserved in ptp interrupt registers. This forced to not use the generic implementation of global/port interrupt method routine. This patch implement the ptp interrupt mechanism to read the timestamp register for sync, pdelay_req and pdelay_resp. Signed-off-by:

This patch is used for reconstructing the absolute time from the 32bit hardware time stamping value. The do_aux ioctl is used for reading the ptp hardware clock and store it to global variable. The timestamped value in tail tag during rx and register during tx are 32 bit value (2 bit seconds and 30 bit nanoseconds). The time taken to read entire ptp clock will be time consuming. In order to speed up, the software clock is maintained. This clock time will be added to 32 bit timestamp to get the absolute time stamp. Signed-off-by:

When the PTP is enabled in hardware bit 6 of PTP_MSG_CONF1 register, the transmit frame needs additional 4 bytes before the tail tag. It is needed for all the transmission packets irrespective of PTP packets or not. The 4-byte timestamp field is 0 for frames other than Pdelay_Resp. For the one-step Pdelay_Resp, the switch needs the receive timestamp of the Pdelay_Req message so that it can put the turnaround time in the correction field. Since PTP has to be enabled for both Transmission and reception timestamping, driver needs to track of the tx and rx setting of the all the user ports in the switch. Two flags hw_tx_en and hw_rx_en are added in ksz_port to track the timestampping setting of each port. When any one of ports has tx or rx timestampping enabled, bit 6 of PTP_MSG_CONF1 is set and it is indicated to tag_ksz.c through tagger bytes. This flag adds 4 additional bytes to the tail tag. When tx and rx timestamping of all the ports are disabled, then 4 bytes are not added. Tested using hwstamp -i <interface> Signed-off-by:

While reviewing dependencies in some Kconfig files, I noticed the redundant dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always, since its introduction, been dependent on the config PCI. So, it is sufficient to just depend on PCI_MSI, and know that the dependency on PCI is implicitly implied. Reduce the dependencies of some network driver configs. No functional change and effective change of Kconfig dependendencies. Signed-off-by:
