2018-07-31wil6210: add 3-MSI supportAlexei Avshalom Lazar
Extend MSI support to 3-MSI in order to load balance the tx\rx interrupts between different cores. use_msi module parameter has changed to n_msi. Usage: - Set n_msi to 0 for using INTx - Set n_msi to 1 for using single MSI - Set n_msi to 3 for using 3-MSI In 3-MSI configuration MSI 0 is used for TX interrupts, MSI 1 is used for RX interrupts and MSI 2 is used for MISC interrupts.

2018-07-31wil6210: fix RX checksum report to network stackMaya Erez
Currently the driver sets CHECKSUM_UNNECESSARY only in case the HW doesn't report checksum error. As ip_summed value is not initialized it is not clear what the driver will report to the network stack in case of HW checksum error or in case HW doesn't calculate checksum. Initialize ip_summed to CHECKSUM_NONE to guarantee checksum calculation by the network stack in the above cases.

2018-07-31ath9k_hw: fix channel maximum power level testFelix Fietkau
The tx power applied by set_txpower is limited by the CTL (conformance test limit) entries in the EEPROM. These can change based on the user configured regulatory domain. Depending on the EEPROM data this can cause the tx power to become too limited, if the original regdomain CTLs impose lower limits than the CTLs of the user configured regdomain. To fix this issue, set the initial channel limits without any CTL restrictions and only apply the CTL at run time when setting the channel and the real tx power.

2018-07-31ath10k: prevent active scans on potential unusable channelsSven Eckelmann
The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the scan. This results in transmission (probe requests) on channels which are not "available" for transmissions. Since the firmware is closed source and nothing can be done from our side to fix the problem in it, the driver has to work around this problem. The WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not scan actively on a channel unless an AP was detected on it. Simple probe requests will then be transmitted by the STA on the channel. ath10k must therefore also use this flag when it queues a radar channel for scanning. This should reduce the chance of an active scan when the channel might be "unusable" for transmissions.

2018-07-30ath10k: add debugfs file warm_hw_resetMaharaja Kennadyrajan
Debugfs support to do hardware warm reset with WMI command WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi service is enabled in the firmware for backward compatibility). This change is purely for debugging purpose when hardware hangs/mutes. This hardware reset won't affect the connectivity but there will be small pause in data traffic. Here we are doing BB/MAC level reset and hence whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset. So the target will be in the active state.

2018-07-30ath10k: disable bundle mgmt tx completion event supportSurabhi Vishnoi
The tx completion of multiple mgmt frames can be bundled in a single event and sent by the firmware to host, if this capability is not disabled explicitly by the host. If the host cannot handle the bundled mgmt tx completion, this capability support needs to be disabled in the wmi init cmd, sent to the firmware. Add the host capability indication flag in the wmi ready command, to let firmware know the features supported by the host driver. This field is ignored if it is not supported by firmware. Set the host capability indication flag(i.e. host_capab) to zero, for disabling the support of bundle mgmt tx completion. This will indicate the firmware to send completion event for every mgmt tx completion, instead of bundling them together and sending in a single event.

2018-07-23net: ethernet: ti: cpsw: add CBS Qdisc offloadIvan Khoronzhuk
The cpsw has up to 4 FIFOs per port and upper 3 FIFOs can feed rate limited queue with shaping. In order to set and enable shaping for those 3 FIFOs queues the network device with CBS qdisc attached is needed. The CBS configuration is added for dual-emac/single port mode only, but potentially can be used in switch mode also, based on switchdev for instance. Despite the FIFO shapers can work w/o cpdma level shapers the base usage must be in combine with cpdma level shapers as described in TRM, that are set as maximum rates for interface queues with sysfs. One of the possible configuration with txq shapers and CBS shapers: Configured with echo RATE > /sys/class/net/eth0/queues/tx-0/tx_maxrate /--------------------------------------------------- / / cpdma level shapers +----+ +----+ +----+ +----+ +----+ +----+ +----+ +----+ | c7 | | c6 | | c5 | | c4 | | c3 | | c2 | | c1 | | c0 | \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \/ \/ \/ \/ \/ \/ \/ \/ +---------|------|------|------|-------------------------------------+ | +----+ | | +---+ | | | +----+ | | | | v v v v | | +----+ +----+ +----+ +----+ p p+----+ +----+ +----+ +----+ | | | | | | | | | | o o| | | | | | | | | | | f3 | | f2 | | f1 | | f0 | r CPSW r| f3 | | f2 | | f1 | | f0 | | | | | | | | | | | t t| | | | | | | | | | \ / \ / \ / \ / 0 1\ / \ / \ / \ / | | \ X \ / \ / \ / \ / \ / \ / \ / | | \/ \ \/ \/ \/ \/ \/ \/ \/ | +-------\------------------------------------------------------------+ \ \ FIFO shaper, set with CBS offload added in this patch, \ FIFO0 cannot be rate limited ------------------------------------------------------ CBS shaper configuration is supposed to be used with root MQPRIO Qdisc offload allowing to add sk_prio->tc->txq maps that direct traffic to appropriate tx queue and maps L2 priority to FIFO shaper. The CBS shaper is intended to be used for AVB where L2 priority (pcp field) is used to differentiate class of traffic. So additionally vlan needs to be created with appropriate egress sk_prio->l2 prio map. If CBS has several tx queues assigned to it, the sum of their bandwidth has not overlap bandwidth set for CBS. It's recomended the CBS bandwidth to be a little bit more. The CBS shaper is configured with CBS qdisc offload interface using tc tool from iproute2 packet. For instance: $ tc qdisc replace dev eth0 handle 100: parent root mqprio num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 1 $ tc -g class show dev eth0 +---(100:ffe2) mqprio |    +---(100:3) mqprio |    +---(100:4) mqprio |     +---(100:ffe1) mqprio |    +---(100:2) mqprio |     +---(100:ffe0) mqprio     +---(100:1) mqprio $ tc qdisc add dev eth0 parent 100:1 cbs locredit -1440 \ hicredit 60 sendslope -960000 idleslope 40000 offload 1 $ tc qdisc add dev eth0 parent 100:2 cbs locredit -1470 \ hicredit 62 sendslope -980000 idleslope 20000 offload 1 The above code set CBS shapers for tc0 and tc1, for that txq0 and txq1 is used. Pay attention, the real set bandwidth can differ a bit due to discreteness of configuration parameters. Here parameters like locredit, hicredit and sendslope are ignored internally and are supposed to be set with assumption that maximum frame size for frame - 1500. It's supposed that interface speed is not changed while reconnection, not always is true, so inform user in case speed of interface was changed, as it can impact on dependent shapers configuration.

2018-07-23net: ethernet: ti: cpsw: use cpdma channels in backward order for txqIvan Khoronzhuk
The cpdma channel highest priority is from hi to lo number. The driver has limited number of descriptors that are shared between number of cpdma channels. Number of queues can be tuned with ethtool, that allows to not spend descriptors on not needed cpdma channels. In AVB usually only 2 tx queues can be enough with rate limitation. The rate limitation can be used only for hi priority queues. Thus, to use only 2 queues the 8 has to be created. It's wasteful. So, in order to allow using only needed number of rate limited tx queues, save resources, and be able to set rate limitation for them, let assign tx cpdma channels in backward order to queues.

2018-07-23net/mlx5e: Use PARTIAL_GSO for UDP segmentationBoris Pismenny
This patch removes the splitting of UDP_GSO_L4 packets in the driver, and exposes UDP_GSO_L4 as a PARTIAL_GSO feature. Thus, the network stack is not responsible for splitting the packet into two.

2018-07-23net/mlx5e: Remove redundant WARN when we cannot find neigh entryRoi Dayan
It is possible for neigh entry not to exist if it was cleaned already. When we bring down an interface the neigh gets deleted but it could be that our listener for neigh event to clear the encap valid bit didn't start yet and the neigh update last used work is started first. In this scenario the encap entry has valid bit set but the neigh entry doesn't exist.
