2018-10-05wlcore: Add support for optional wakeirqTony Lindgren
Now with wlcore using PM runtime, we can also add support for Linux generic wakeirq handling for it if configured in the dts file. The wakeirq can be configured as the second interrupt in the dts file with interrupts-extended property where it is the padconf irq of the OOB GPIO pin used for wlcore interrupt. Note that eventually we should also allow configuring wlcore to use the SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be configured to be the padconf interrupt of the dat1 pin and not the padconf interrupt of the OOB GPIO pin.

2018-10-05wlcore: Fix BUG with clear completion on timeoutTony Lindgren

2018-10-05brcmfmac: fix full timeout waiting for action frame on-channel txChung-Hsien Hsu
The driver sends an action frame down and waits for a completion signal triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event to continue the process. However, the action frame could be transmitted either on the current channel or on an off channel. For the on-channel case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when the frame is transmitted, which make the driver always wait a full timeout duration. This patch has the completion signal be triggered by receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel case. This change fixes WFA p2p certification 5.1.19 failure.

2018-10-05brcmfmac: reduce timeout for action frame scanChung-Hsien Hsu
Finding a common channel to send an action frame out is required for some action types. Since a loop with several scan retry is used to find the channel, a short wait time could be considered for each attempt. This patch reduces the wait time from 1500 to 450 msec for each action frame scan. This patch fixes the WFA p2p certification 5.1.20 failure caused by the long action frame send time.

2018-10-02hv_netvsc: remove ndo_poll_controllerStephen Hemminger
Similar to other patches from ERic. As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. In netvsc driver it uses NAPI for TX completions. The default poll_napi will do this for us now and avoid the capture.

Currently there is no support for dynamic interrupt moderation. This patch adds some initial code to support this. The following changes were made: 1. Currently we are using multiple members to store the interrupt granularity (itr_gran_25/50/100/200). This is not necessary because we can query the device to determine what the interrupt granularity should be set to, done by a new function ice_get_itr_intrl_gran. 2. Added intrl to ice_q_vector structure to support interrupt rate limiting. 3. Added the function ice_intrl_usecs_to_reg for converting to a value in usecs that the device understands. 4. Added call to write to the GLINT_RATE register. Disable intrl by default for now. 5. Changed rx/tx_itr_setting to itr_setting because having both seems redundant because a ring is either Tx or Rx. 6.

2018-10-02ice: Split irq_tracker into sw_irq_tracker and hw_irq_trackerPreethi Banala
For the PF driver, when mapping interrupts to queues, we need to request IRQs from the kernel and we also have to allocate interrupts from the device. Similarly, when the VF driver (iavf.ko) initializes, it requests the kernel IRQs that it needs but it can't directly allocate interrupts in the device. Instead, it sends a mailbox message to the ice driver, which then allocates interrupts in the device on the VF driver's behalf. Currently both these cases end up having to reserve entries in pf->irq_tracker but irq_tracker itself is sized based on how many vectors the PF driver needs. Under the right circumstances, the VF driver can fail to get entries in irq_tracker, which will result in the VF driver failing probe. To fix this, sw_irq_tracker and hw_irq_tracker are introduced. The sw_irq_tracker tracks only the PF's IRQ request and doesn't play any role in VF init. hw_irq_tracker represents the device's interrupt space. When interrupts have to be allocated in the device for either PF or VF, hw_irq_tracker will be looked up to see if the device has run out of interrupts.

2018-10-02ice: Implement VSI replay frameworkAnirudh Venkataramanan
Currently, switch filters get replayed after reset. In addition to filters, other VSI attributes (like RSS configuration, Tx scheduler configuration, etc.) also need to be replayed after reset. Thus, instead of replaying based on functional blocks (i.e. replay all filters for all VSIs, followed by RSS configuration replay for all VSIs, and so on), it makes more sense to have the replay centered around a VSI. In other words, replay all configurations for a VSI before moving on to rebuilding the next VSI. To that effect, this patch introduces a VSI replay framework in a new function ice_vsi_replay_all. Currently it only replays switch filters, but it will be expanded in the future to replay additional VSI attributes.

2018-10-01ibmvnic: Add ethtool private flag for driver-defined queue limitsThomas Falcon
When choosing channel amounts and ring sizes, the maximums in the ibmvnic driver are defined by the virtual i/o server management partition. Even though they are defined as maximums, the client driver may in fact successfully request resources that exceed these limits, which are mostly dependent on a user's hardware With this in mind, provide an ethtool flag that when enabled will allow the user to request resources limited by driver-defined maximums instead of limits defined by the management partition. The driver will try to honor the user's request but may not allowed by the management partition. In this case, the driver requests as close as it can get to the desired amount until it succeeds.

During bcm_sysport_insert_tsb() make sure we differentiate a SKB headroom re-allocation failure from the normal swap and replace path. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-10-01net: systemport: Turn on offloads by defaultFlorian Fainelli
We can turn on the RX/TX checksum offloads by default and make sure that those are properly reflected back to e.g: stacked devices such as VLAN or DSA. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

During driver resume and open, the HW may have lost its context/state, utilize bcm_sysport_set_features() to make sure we do restore the correct set of features that were previously configured.

2018-10-01net: systemport: Refactor bcm_sysport_set_features()Florian Fainelli
In preparation for unconditionally enabling TX and RX checksum offloads, refactor bcm_sysport_set_features() a bit such that __netdev_update_features() during register_netdev() can make sure that features are correctly programmed during network device registration. Since we can now be called during register_netdev() with clocks gated, we need to temporarily turn them on/off in order to have a successful register programming. We also move the CRC forward setting read into bcm_sysport_set_features() since priv->crc_fwd matters while turning on RX checksum offload, that way we are guaranteed they are in sync in case we ever add support for NETIF_F_RXFCS at some point in the future.

2018-10-01net: hns3: Add input key and action config support for flow directorJian Shen
Each flow director rule consists of input key and action. The input key is the condition for matching, includes tuples of L2/L3/L4 header. Action is the behaviour when a packet matches with the input key, such as drop the packet, or forward to a specified queue. The input key is stored in the tcam blocks, Each bit of input key can be masked.
