2019-09-13rtw88: add dynamic cck pd mechanismTzu-En Huang
This mechanism reduces the numbers of false alram in cck rate by dynamically adjusting the value of power threshold and cs_ratio. We determine the new value by three factors, which are rssi, false alarm count and igi. Based on these factors, we define the current condition into five levels. Compared to the previous level, if the level is changed, we set the new values for power threshold and cs_ratio.

Since 8822c requires to do not only IQK, but also DPK. Move these calibrations that need to be done once the channel is determined, into phy_calibration.

2019-09-13rtw88: 8822c: add SW DPK supportTzu-En Huang
Power amplifiers are not linear components, and require DPK to reduce its nonlinearity. DPK is called Digital Pre-distortion Calibration, can be used to compensate the output of power. DPK tracking is in charge of tracking the thermal changes. And it then shifts the power curve accordingly, which makes the power output remains linear even if the PA works in different temperature. To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate.

2019-09-13rtw88: 8822c: add FW IQK supportYan-Hsuan Chuang
Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get.

Port the same fix for ixgbe to ixgbevf. The ixgbevf driver currently does IPsec Tx offloading based on an existing secpath. However, the secpath can also come from the Rx side, in this case it is misinterpreted for Tx offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for Tx offload.

Lukasz fixes how the firmware version is stored to align with how the firmware stores its own version. Also extended the log message to display additional useful information such as NVM version, API patch information and firmware build hash.

Wenwen Wang fixes a potential memory leak where 3 allocated variables are not properly cleaned up on failure for ixgbe. Stefan Assmann fixes a potential kernel panic found when repeatedly spawning and destroying VFs in i40e when a NULL pointer is dereferenced due to a race condition. Fixed up the i40e driver to clear the __I40E_VIRTCHNL_OP_PENDING bit before returning after an invalid minimum transmit rate is requested. Updates the iavf driver to only apply the MAC address change when the PF ACK's the requested change. Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call instead of the driver accessing the queue mapping directly. Jake updates i40e to use ktime_get_real_ts64() instead of ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud filters, since it is a reserved bit and not a valid type. Also added code comments to clearly state which bits are reserved and should not be used or defined for cloud filter adminq command. Clarify the macros used to specify the cloud filter fields are individual bits, so use the BIT() macro. Aleksandr fixes up the print_link_message() to include the "negotiated" FEC status for i40e. Czeslaw also adds additional log message for devices without FEC in the print_link_message() for i40e. Colin Ian King reduces the object code size by making the array API static constant. Magnus fixes a potential receive buffer starvation issue for AF_XDP by kicking the NAPI context of any queue with an attached AF_XDP zero-copy socket. v2: Removed patch 11 from the original series (Alex Duyck's ITR fix), so that it can be sent to the net tree. ==================== Signed-off-by: David S.

2019-09-12wil6210: ignore reset errors for FW during probeLior David
There are special kinds of FW such as WMI only which are used for testing, diagnostics and other specific scenario. Such FW is loaded during driver probe and the driver disallows enabling any network interface, to avoid operational issues. In many cases it is used to debug early versions of FW with new features, which sometimes fail on startup. Currently when such FW fails to load (for example, because of init failure), the driver probe would fail and shutdown the device making it difficult to debug the early failure. To fix this, ignore load failures in WMI only FW and allow driver probe to succeed, making it possible to continue and debug the FW load failure.

2019-09-12ath10k: fix channel info parsing for non tlv targetRakesh Pillai
The tlv targets such as WCN3990 send more data in the chan info event, which is not sent by the non tlv targets. There is a minimum size check in the wmi event for non-tlv targets and hence we cannot update the common channel info structure as it was done in commit 13104929d2ec ("ath10k: fill the channel survey results for WCN3990 correctly"). This broke channel survey results on 10.x firmware versions. If the common channel info structure is updated, the size check for chan info event for non-tlv targets will fail and return -EPROTO and we see the below error messages ath10k_pci 0000:01:00.0: failed to parse chan info event: -71 Add tlv specific channel info structure and restore the original size of the common channel info structure to mitigate this issue.

2019-09-12ath10k: adjust skb length in ath10k_sdio_mbox_rx_packetNicolas Boichat
When the FW bundles multiple packets, pkt->act_len may be incorrect as it refers to the first packet only (however, the FW will only bundle packets that fit into the same pkt->alloc_len). Before this patch, the skb length would be set (incorrectly) to pkt->act_len in ath10k_sdio_mbox_rx_packet, and then later manually adjusted in ath10k_sdio_mbox_rx_process_packet. The first problem is that ath10k_sdio_mbox_rx_process_packet does not use proper skb_put commands to adjust the length (it directly changes skb->len), so we end up with a mismatch between skb->head + skb->tail and skb->data + skb->len. This is quite serious, and causes corruptions in the TCP stack, as the stack tries to coalesce packets, and relies on skb->tail being correct (that is, skb_tail_pointer must point to the first byte_after_ the data). Instead of re-adjusting the size in ath10k_sdio_mbox_rx_process_packet, this moves the code to ath10k_sdio_mbox_rx_packet, and also add a bounds check, as skb_put would crash the kernel if not enough space is available. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.

2019-09-12ath10k: free beacon buf later in vdev teardownBen Greear
My wave-1 firmware often crashes when I am bringing down AP vdevs, and sometimes at least some machines lockup hard after spewing IOMMU errors. I don't see the same issue in STA mode, so I suspect beacons are the issue. Moving the beacon buf deletion to later in the vdev teardown logic appears to help this problem. Firmware still crashes often, but several iterations did not show IOMMU errors and machine didn't hang.

2019-09-12ixgbe: Fix secpath usage for IPsec TX offload.Steffen Klassert
The ixgbe driver currently does IPsec TX offloading based on an existing secpath. However, the secpath can also come from the RX side, in this case it is misinterpreted for TX offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for TX offload.
