2020-05-08iwlwifi: mvm: set properly station flags in STA_HE_CTXT_CMDShaul Triebitz1-5/+9
For ACK_ENABLED and 32BIT_BA_BITMAP flags check the station capabilities rather than bss_conf.ack_enabled and bss_conf.multi_sta_back_32bit. These fields are stations capabilities and should not be in bss_conf. Also note that the bss_conf flags are set in station mode only. In the next patch I will remove ack_enabled and multi_sta_back_32bit from the bss_conf structure.

2020-05-08iwlwifi: avoid debug max amsdu config overwriting itselfMordechay Goodstein2-11/+15
If we set amsdu_len one after another the second one overwrites the orig_amsdu_len so allow only moving from debug to non debug state. Also the TLC update check was wrong: it was checking that also the orig is smaller then the new updated size, which is not the case in debug amsdu mode.

Currently, bonding always returns NETDEV_TX_OK to its caller.

2020-05-08net: dsa: sja1105: implement tc-gate using time-triggered virtual linksVladimir Oltean10-17/+759
Restrict the TTEthernet hardware support on this switch to operate as closely as possible to IEEE 802.1Qci as possible. This means that it can perform PTP-time-based ingress admission control on streams identified by {DMAC, VID, PCP}, which is useful when trying to ensure the determinism of traffic scheduled via IEEE 802.1Qbv. The oddity comes from the fact that in hardware (and in TTEthernet at large), virtual links always need a full-blown action, including not only the type of policing, but also the list of destination ports. So in practice, a single tc-gate action will result in all packets getting dropped. Additional actions (either "trap" or "redirect") need to be specified in the same filter rule such that the conforming packets are actually forwarded somewhere. Apart from the VL Lookup, Policing and Forwarding tables which need to be programmed for each flow (virtual link), the Schedule engine also needs to be told to open/close the admission gates for each individual virtual link. A fairly accurate (and detailed) description of how that works is already present in sja1105_tas.c, since it is already used to trigger the egress gates for the tc-taprio offload (IEEE 802.1Qbv). Key point here, we remember that the schedule engine supports 8 "subschedules" (execution threads that iterate through the global schedule in parallel, and that no 2 hardware threads must execute a schedule entry at the same time). For tc-taprio, each egress port used one of these 8 subschedules, leaving a total of 4 subschedules unused. In principle we could have allocated 1 subschedule for the tc-gate offload of each ingress port, but actually the schedules of all virtual links installed on each ingress port would have needed to be merged together, before they could have been programmed to hardware. So simplify our life and just merge the entire tc-gate configuration, for all virtual links on all ingress ports, into a single subschedule. Be sure to check that against the usual hardware scheduling conflicts, and program it to hardware alongside any tc-taprio subschedule that may be present. The following scenarios were tested: 1.

Implement tc-flower offloads for redirect, trap and drop using non-critical virtual links. Commands which were tested to work are: # Send frames received on swp2 with a DA of 42:be:24:9b:76:20 to the # CPU and to swp3. This type of key (DA only) when the port's VLAN # awareness state is off. tc qdisc add dev swp2 clsact tc filter add dev swp2 ingress flower skip_sw dst_mac 42:be:24:9b:76:20 \ action mirred egress redirect dev swp3 \ action trap # Drop frames received on swp2 with a DA of 42:be:24:9b:76:20, a VID # of 100 and a PCP of 0. tc filter add dev swp2 ingress protocol 802.1Q flower skip_sw \ dst_mac 42:be:24:9b:76:20 vlan_id 100 vlan_prio 0 action drop Under the hood, all rules match on DMAC, VID and PCP, but when VLAN filtering is disabled, those are set internally by the driver to the port-based defaults. Because we would be put in an awkward situation if the user were to change the VLAN filtering state while there are active rules (packets would no longer match on the specified keys), we simply deny changing vlan_filtering unless the list of flows offloaded via virtual links is empty. Then the user can re-add new rules. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-05-08net: dsa: introduce a dsa_port_from_netdev public helperVladimir Oltean2-0/+10
As its implementation shows, this is synonimous with calling dsa_slave_dev_check followed by dsa_slave_to_port, so it is quite simple already and provides functionality which is already there. However there is now a need for these functions outside dsa_priv.h, for example in drivers that perform mirroring and redirection through tc-flower offloads (they are given raw access to the flow_cls_offload structure), where they need to call this function on act->dev. But simply exporting dsa_slave_to_port would make it non-inline and would result in an extra function call in the hotpath, as can be seen for example in sja1105: Before: 000006dc <sja1105_xmit>: { 6dc: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr} 6e0: e1a04000 mov r4, r0 6e4: e591958c ldr r9, [r1, #1420] ; 0x58c <- Inline dsa_slave_to_port 6e8: e1a05001 mov r5, r1 6ec: e24dd004 sub sp, sp, #4 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 6f0: e1c901d8 ldrd r0, [r9, #24] 6f4: ebfffffe bl 0 <dsa_8021q_tx_vid> 6f4: R_ARM_CALL dsa_8021q_tx_vid u8 pcp = netdev_txq_to_tc(netdev, queue_mapping); 6f8: e1d416b0 ldrh r1, [r4, #96] ; 0x60 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 6fc: e1a08000 mov r8, r0 After: 000006e4 <sja1105_xmit>: { 6e4: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr} 6e8: e1a04000 mov r4, r0 6ec: e24dd004 sub sp, sp, #4 struct dsa_port *dp = dsa_slave_to_port(netdev); 6f0: e1a00001 mov r0, r1 { 6f4: e1a05001 mov r5, r1 struct dsa_port *dp = dsa_slave_to_port(netdev); 6f8: ebfffffe bl 0 <dsa_slave_to_port> 6f8: R_ARM_CALL dsa_slave_to_port 6fc: e1a09000 mov r9, r0 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 700: e1c001d8 ldrd r0, [r0, #24] 704: ebfffffe bl 0 <dsa_8021q_tx_vid> 704: R_ARM_CALL dsa_8021q_tx_vid Because we want to avoid possible performance regressions, introduce this new function which is designed to be public.

Changes all over, ath10k apparently seeing most new features this time. rtw88 also had lots of changes due to preparation for new hardware support. In this pull request there's also a new macro to include/linux/iopoll: read_poll_timeout_atomic(). This is needed by rtw88 for atomic polling. Major changes: ath11k * add debugfs file for testing ADDBA and DELBA * add 802.11 encapsulation offload on hardware support * add htt_peer_stats_reset debugfs file ath10k * enable VHT160 and VHT80+80 modes * enable radar detection in secondary segment * sdio: disable TX complete indication to improve throughput * sdio: decrease power consumption * sdio: add HTT TX bundle support to increase throughput * sdio: add rx bitrate reporting ath9k * improvements to AR9002 calibration logic carl9170 * remove buggy P2P_GO support p54usb * add support for AirVasT USB stick rtw88 * add support for antenna configuration ti wlcore * add support for AES_CMAC cipher iwlwifi * support for a few new FW API versions * new hw configs ==================== Signed-off-by: David S.

2020-05-07Merge branch 'Add-QRTR-MHI-client-driver'David S. Miller3-1/+136
Manivannan Sadhasivam says: ==================== Add QRTR MHI client driver Here is the series adding MHI client driver support to Qualcomm IPC router protocol. MHI is a newly added bus to kernel which is used to communicate to external modems over a physical interface like PCI-E. This driver is used to transfer the QMI messages between the host processor and external modems over the "IPCR" channel. For QRTR, this driver is just another driver acting as a transport layer like SMD. Currently this driver is needed to control the QCA6390 WLAN device from ath11k. The ath11k MHI controller driver will take care of booting up QCA6390 and bringing it to operating state. Later, this driver will be used to transfer QMI messages over the MHI-IPCR channel. The second patch of this series removes the ARCH_QCOM dependency for QRTR. This is needed because the QRTR driver will be used with x86 machines as well to talk to devices like QCA6390. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2020-05-07net: qrtr: Do not depend on ARCH_QCOMManivannan Sadhasivam1-1/+0
IPC Router protocol is also used by external modems for exchanging the QMI messages. Hence, it doesn't always depend on Qualcomm platforms. One such instance is the QCA6390 WLAN device connected to x86 machine.
