The scan request processing populated the direct SSIDs in the FW scan request command also for 6GHz scan, which is not needed and might result in unexpected behavior. Fix the code to add the direct SSIDs only in case the scan is not a 6GHz scan. Signed-off-by:

If the firmware crashes while we're waiting for the reset handshake then it cannot possibly make progress anymore, and we will just time out the wait. That's pointless, so just stop waiting at that point. Additionally, if it never acknowledges the reset handshake, something went wrong. Dump an error in both of these cases, but we need to do it synchronously here since the device will be turned off. Signed-off-by:

When switching op-modes, or more generally when reconfiguring, we might switch the RB size. In _iwl_pcie_rx_init() we have a comment saying we must free all RBs since we might switch the size, but this is actually too late: the switch has been done and we'll free the buffers with the wrong size. Fix this by always freeing the buffers, if any, at the start of configure, instead of only after the size may have changed. Signed-off-by:

Juhee Kang says: ==================== samples: pktgen: enhance the ability to print the execution results of samples This patch series improves the ability to print the execution result of pktgen samples by adding a line which calls the function before termination and adding trap SIGINT. Also, this series documents the latest pktgen usage options. Currently, pktgen samples print the execution result when terminated usually. However, sample03 is not working properly. This is results of sample04 and sample03: # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 1 Running... ctrl^C to stop Device: eth0@0 Result: OK: 19(c5+d13) usec, 1 (60byte,0frags) 51762pps 24Mb/sec (24845760bps) errors: 0 # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample03_burst_single_flow.sh -n 1 Running... ctrl^C to stop Because sample03 doesn't call the function which prints the execution result when terminated normally, unlike other samples. So the first commit solves this issue by adding a line which calls the function before termination. Also, all pktgen samples are able to send infinite messages per thread by setting the count option to 0, and pktgen is stopped by Ctrl-C. However, the sample besides sample{3...5} don't work appropriately because Ctrl-C stops the script, not just pktgen. This is results of samples: # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 0 Running... ctrl^C to stop ^CDevice: eth0@0 Result: OK: 569657(c569538+d118) usec, 84650 (60byte,0frags) 148597pps 71Mb/sec (71326560bps) errors: 0 # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -n 0 Running... ctrl^C to stop ^C # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample02_multiqueue.sh -n 0 Running... ctrl^C to stop ^C # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample06_numa_awared_queue_irq_affinity.sh -n 0 Running... ctrl^C to stop ^C # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_bench_xmit_mode_netif_receive.sh -n 0 Running... ctrl^C to stop ^C # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_bench_xmit_mode_queue_xmit.sh -n 0 Running... ctrl^C to stop ^C So the second commit solves this issue by adding trap SIGINT. Also, changes control_c function to print_results to maintain consistency with other samples on the first commit and second commit. And current pktgen.rst documentation doesn't add the latest pktgen sample usage options such as count and IPv6, and so on. Also, the old pktgen sample scripts are still included in the document. The old scripts were removed by the commit a4b6ade8 ("samples/pktgen: remove remaining old pktgen sample scripts"). Thus, the last commit documents the latest pktgen sample usage and removes old sample scripts. And fixes a minor typo. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

All pktgen samples can send indefinitely num messages per thread by setting the count option to 0(-n 0). If running sample with setting count 0 and press Ctrl-C to stop this program, the program prints the result of the execution so far. Currently, the samples besides sample{3...5} don't work properly. Because Ctrl-C stops the script, not just pktgen. This is results of samples: # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 0 Running... ctrl^C to stop ^CDevice: eth0@0 Result: OK: 569657(c569538+d118) usec, 84650 (60byte,0frags) 148597pps 71Mb/sec (71326560bps) errors: 0 # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -n 0 Running... ctrl^C to stop ^C In order to solve this, this commit adds trap SIGINT.

Sunil Goutham says: ==================== Octeontx2: Traffic shaping and SDP link config support This patch series adds support for traffic shaping configuration on all silicons available after 96xx C0. And also adds SDP link related configuration needed when Octeon is connected as an end-point and traffic needs to flow from end-point to host and vice versa. Series also has other changes like - New mbox messages in admin function driver for PF/VF drivers to retrieve available HW resource count. HW resources like block LFs, bandwidth profiles etc are covered. - Added PTP device ID for new CN10K and 95O silicons. - etc ==================== Signed-off-by: -

CN10K slicon has different device id for PTP device. Hence this patch updates the driver with new id. Though ptp driver being a separate driver AF manages configuring PTP block by all PFs. To manage ptp, AF driver checks in its probe whether 1. ptp hardware device found on silicon 2. A driver is bound to ptp device 3. The ptp driver probe is successful In failure of cases 1 and 3, AF proceeds with out ptp and for case 2 defers the probe. This patch refactors code also to check for all the PTP device ids given in ptp device ids table for case 1. Also added PTP device ID for 95O silicon Signed-off-by:

In 98xx, there are 2 NIX blocks and 4 LBK blocks present. The way these NIX-LBK should be configured depends on the use case. By default loopback functionality is supported in AF VF pairs which are attached to NIX0 and NIX1 LFs alternatively to ensure load balancing. NIX0 transmits a packet to LBK1 which will be received by NIX1 and packet transmitted by NIX1 will get received by NIX0 via LBK2. There are some requirements where only one AF VF is used and respective NIX is expected to operate in a mode where it can receive it own packet back. This can be achieved if NIX0 sends packet to LBK0 and not LBK1. Adding a flag in LF alloc request mailbox which can setup NIX0 to use LBK0 and NIX1 can use LBK3. Signed-off-by:

Before C0 HW revision, The RSS adder was computed based the following static formula. rss_adder<7:0> = flow_tag<7:0> ^ flow_tag<15:8> ^ flow_tag<23:16> ^ flow_tag<31:24> The above scheme has the following drawbacks: 1) It is not in line with other standard NIC behavior. 2) There can be an SW use case where SW can compute the hash upfront using Toeplitz function and predict the queue selection to optimize some packet lookup function. The nonstandard way of doing XOR makes the consumer to not predict the queue selection. C0 HW revision onwards, The HW can configure the rss_adder<7:0> as flow_tag<7:0> to align with standard NICs. This patch adds an option to select legacy RSS adder mode vs standard NIC behavior by setting NIX_LF_RSS_TAG_LSB_AS_ADDER flag. Since this bit field is used as reserved in old HW revisions, No need to have an additional HW version check. Signed-off-by:

NIX_AF_TX_LINKX_NORM_CREDIT holds running counter of tx credits available per link. But, tx credits should be configured based on MTU config. So MTU change needs tx credit count update. An issue exists whereby when both PF & VF are enabled and PF traffic is flowing, if VF requests for MTU update, updating the NORM_CREDIT register will lead to corruption of credit count and subsequent deadlock of tx link as the NORM_CREDIT register holds running count. This patch provides workaround by pausing link traffic using NIX_AF_TL1X_SW_XOFF, waiting for existing packets to drain, and used credits be returned before updating new credit count. Signed-off-by:

Biju Das says: ==================== Add Factorisation code to support Gigabit Ethernet driver The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are similar to the R-Car Ethernet AVB IP. The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller (DMAC). With a few changes in the driver we can support both IPs. This patch series aims to add factorisation code to support RZ/G2L SoC, hardware feature bits for gPTP feature, Multiple irq feature and optional reset support.
