Do not cancel scan in disconnect callback. If there is an active scan, it will be cancelled by firmware, then host driver will be properly notified by event. Cancelling scan in disconnect callback occasionally may lead to the following race issue. Host is able to queue one scan after scan abort in disconnect callback, and another scan after scan abort in event handler. As a result, firmware receives second scan before the first scan completes.

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.

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.

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.

Presently, for non-zero copy case, separate pages are allocated for storing plaintext and encrypted text of records. These pages are stored in sg_plaintext_data and sg_encrypted_data scatterlists inside record structure. Further, sg_plaintext_data & sg_encrypted_data are passed to cryptoapis for record encryption. Allocating separate pages for plaintext and encrypted text is inefficient from both required memory and performance point of view. This patch adds support of inplace encryption of records. For non-zero copy case, we reuse the pages from sg_encrypted_data scatterlist to copy the application's plaintext data. For the movement of pages from sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new function move_to_plaintext_sg(). This function add pages into sg_plaintext_data from sg_encrypted_data scatterlists. tls_do_encryption() is modified to pass the same scatterlist as both source and destination into aead_request_set_crypt() if inplace crypto has been enabled. A new ariable 'inplace_crypto' has been introduced in record structure to signify whether the same scatterlist can be used. By default, the inplace_crypto is enabled in get_rec(). If zero-copy is used (i.e. plaintext data is not copied), inplace_crypto is set to '0'.

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.

It is useful to be able to use the same socket for listening in a specific VRF, as for sending multicast packets out of a specific interface. However, the bound device on the socket currently takes precedence and results in the packets not being sent.

While the old field was implicitly initialized to 0, the new field is not initialized, resulting in the bridge defaulting to multicast disabled state and breaking existing applications.

Ioana Radulescu says: ==================== dpaa2-eth: Add support for Rx flow classification The Management Complex (MC) firmware initially allowed the configuration of a single key to be used both for Rx flow hashing and flow classification. This prevented us from supporting Rx flow classification independently of the hash key configuration. Newer firmware versions expose separate commands for configuring the two types of keys, so we can use them to introduce Rx classification support. For frames that don't match any classification rule, we fall back to statistical distribution based on the current hash key. The first patch in this set updates the Rx hashing code to use the new firmware API for key config. Subsequent patches introduce the firmware API for configuring the classification and actual support for adding and deleting rules via ethtool. ==================== Signed-off-by: David S.

Add support for inserting and deleting Rx flow classification rules through ethtool. We support classification based on some header fields for flow-types ether, ip4, tcp4, udp4 and sctp4. Rx queues are core affine, so the action argument effectively selects on which cpu the matching frame will be processed. Discarding the frame is also supported.

For firmware versions that support it, configure an Rx flow classification key at probe time. Hardware expects all rules in the classification table to share the same key. So we setup a key containing all supported fields at driver init and when a user adds classification rules through ethtool, we will just mask out the unused header fields. Since the key composition process is the same for flow classification and hashing, reuse existing code where possible.
