2021-08-26iwlwifi: mvm: Add support for hidden network scan on 6GHz bandIlan Peer2-15/+76
Add support for discovery of hidden networks on the 6GHz band, by including the scan request direct SSIDs in the FW scan request command: - In case a short SSID matches one of the direct SSIDs in the scan request command, add the matching SSID in the same offset in the 'direct_ssids' array. - Otherwise, add the SSID in one of the available slots. Additionally, as a preparation to handle hidden APs, refactor iwl_mvm_umac_scan_cfg_channels_v6_6g() the function.

2021-08-26iwlwifi: pcie: dump error on FW reset handshake failuresJohannes Berg3-6/+24
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.

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.

2021-08-26net: dsa: hellcreek: Adjust schedule look ahead windowKurt Kanzenbach1-1/+1
Traffic schedules can only be started up to eight seconds within the future. Therefore, the driver periodically checks every two seconds whether the admin base time provided by the user is inside that window. If so the schedule is started. Otherwise the check is deferred. However, according to the programming manual the look ahead window size should be four - not eight - seconds. By using the proposed value of four seconds starting a schedule at a specified admin base time actually works as expected.

2021-08-26ionic: sync the filters in the work taskShannon Nelson5-37/+247
In order to separate the atomic needs of __dev_uc_sync() and __dev_mc_sync() from the safe rx_mode handling, we need to have the ndo handler manipulate the driver's filter list, and later have the driver sync the filters to the firmware, outside of the atomic context. Here we put __dev_mc_sync() and __dev_uc_sync() back into the ndo callback to give them their netif_addr_lock context and have them update the driver's filter list, flagging changes that should be made to the device filter list. Later, in the rx_mode handler, we read those hints and sync up the device's list as needed. It is possible for multiple add/delete requests to come from the stack before the rx_mode task processes the list, but the handling of the sync status flag should keep everything sorted correctly. For example, if a delete of an existing filter is followed by another add before the rx_mode task is run, as can happen when going in and out of a bond, the add will cancel the delete and no actual changes will be sent to the device. We also add a check in the watchdog to see if there are any stray unsync'd filters, possibly left over from a filter overflow and waiting to get sync'd after some other filter gets removed to make room.

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.

Unlike OcteonTx2, the channel numbers used by CGX/RPM and LBK on CN10K silicons aren't fixed in HW. They are SW programmable, hence we cannot derive transmit link from static channel numbers anymore.

2021-08-25octeontx2-af: Allow to configure flow tag LSB byte as RSS adderJerin Jacob2-6/+13
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.

2021-08-25octeontx2-af: enable tx shaping feature for 96xx C0Nithin Dabilpuram5-37/+281
Starting from 96xx C0 onwards all silicons support traffic shaping. This patch enables that feature along with other changes - When PIR/CIR shaping config is modified, toggle SW_XOFF for config to take effect - Before SMQ flush, clear SW_XOFF at all parent schedulers - Support to read current transmit scheduler configuration via mbox Signed-off-by: Nithin Dabilpuram <ndabilpuram@marvell.com> Signed-off-by: Geetha sowjanya <gakula@marvell.com> Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2021-08-25octeontx2-af: Wait for TX link idle for credits changeNithin Dabilpuram2-11/+92
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.

Clear and disable interrupt before queueing work as there might be a chance that work gets completed on other core faster and interrupt enable as a part of the work completes before interrupt disable in the interrupt context. This leads to permanent disable of interrupt.
