* wil6210: use eth_hw_addr_set()Jakub Kicinski2021-10-201-1/+1
| | | | | | | | | | | | | Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Do the special encoding on the stack, then copy the address.

* wil6210: Add Support for Extended DMG MCS 12.1Max Chen2021-02-091-0/+3
| | | | | | | | | | | FW reports Tx/Rx extended MCS 12.1 to driver as "26". Driver will convert this into base MCS 7 + EXTENDED_SC_DMG flag so kernel can do the correct phy rate conversion. Also add log prints to print "12.1" instead of "26" for extended MCS.

* wil6210: support set_multicast_to_unicast cfg80211 operationAhmad Masri2019-12-191-0/+1
| | | | | | | | | | | | | | | | | | | | Wil6210 AP has a separate ring for transmitting multicast packets, multicast packets are transmitted without an ack from the receiver side. Therefore, 802.11 spec defines some low MCS rates for multicat packets. However, there is no guarantee that these packets were really received and handled on the client side. Some applications that rely on multicast packets, may prefer to transmit these packets as a unicast to ensure reliability, and also to ensure better performance with high MCS rates. multicast to unicast is done by duplicating multicast packets to all clients and changing the DA (multicast) to the MAC address of the client. see NL80211_CMD_SET_MULTICAST_TO_UNICAST for more info.

* wil6210: fix PTK re-key raceAhmad Masri2019-09-121-0/+15
| | | | | | | | | | | | | | | | | Fix a race between cfg80211 add_key call and transmitting of 4/4 EAP packet. In case the transmit is delayed until after the add key takes place, message 4/4 will be encrypted with the new key, and the receiver side (AP) will drop it due to MIC error. Wil6210 will monitor and look for the transmitted packet 4/4 eap key. In case add_key takes place before the transmission completed, then wil6210 will let the FW store the key and wil6210 will notify the FW to use the PTK key only after 4/4 eap packet transmission was completed.

* wil6210: fix wil_cid_valid with negative cid valuesColin Ian King2019-09-041-1/+1
| | | | | | | | | | | | | | | | | | | There are several occasions where a negative cid value is passed into wil_cid_valid and this is converted into a u8 causing the range check of cid >= 0 to always succeed. Fix this by making the cid argument an int to handle any -ve error value of cid. An example of this behaviour is in wil_cfg80211_dump_station, where cid is assigned -ENOENT if the call to wil_find_cid_by_idx fails, and this -ve value is passed to wil_cid_valid. I believe that the conversion of -ENOENT to the u8 value 254 which is greater than wil->max_assoc_sta causes wil_find_cid_by_idx to currently work fine, but I think is by luck and not the intended behaviour.

* wil6210: reset buff id in status message after completionMaya Erez2019-04-031-0/+1
| | | | | | | | | | | | | | | | | Since DR bit and buffer id are written in different dwords of the status message, the DR bit can already be set to 1 while the buffer id is not updated yet. Resetting the buffer id in the status message will allow the driver to identify such cases and re-read the status message until the buffer id is written by HW. In case DR bit is set but buffer id is zero, need to read the status message again, until a valid id is identified. In addition to that, move the completed buffer id to the tail of the free list to prevent its immediate reuse in the upcoming refill.

However, if there is a different MISC ICR before the driver clears this bit, there is a risk of race condition between HALP mask and unmask.

| | | | | | | | | | | | | | | | | | | | In AP mode with multiple clients, driver stops net queue (netif_tx_stop_queue) upon first ring (serving specific client) becoming full. This can have negative effect on transmission to other clients which may still have room in their corresponding rings. Implement new policy in which stop/wake net queue are not used. In case there is no room in the ring for a transmitted packet, drop the packet. New policy can be helpful to debug performance issues, to guarantee maximum utilization of net queues.

* wil6210: add support for enhanced DMA TX data flowsMaya Erez2018-07-021-0/+15
| | | | | | | | | | | | | | | | | | | The enhanced DMA TX data path is handled using a descriptor ring per connection and a single status ring. The driver gets TX completions via the TX status ring. Each status message points to the completed descriptor ring and includes the number of completed descriptors in this ring. Non TSO enhanced DMA TX descriptors are similar to legacy DMA TX descriptors, hence the same transmit function can be used. However, enhanced DMA TSO frames division is performed by the HW, hence a new function is added to handle enhanced DMA TSO.

* wil6210: initialize TX and RX enhanced DMA ringsGidon Studinski2018-07-021-7/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhanced DMA design includes the following rings: - Single RX descriptor ring is used for all VIFs - Multiple RX status rings are supported, to allow RSS - TX descriptor ring is allocated per connection - A single TX status ring is used for all TX descriptor rings This patch initializes and frees the above descriptor and status rings. The RX SKBs are handled by a new entity of RX buffers manager, which handles RX buffers, each one points to an allocated SKB. During Rx completion processing, the driver extracts a buffer ID which is used as an index to the buffers array. After the SKB is freed the buffer is moved from the 'active' list to the 'free' list, indicating it can be used for another descriptor. During Rx refill, SKBs are allocated and attached to 'free' buffers. Those buffers are attached to new descriptors and moved to the 'active' list. New debugfs entries were added to allow edma configuration: Run the following command to configure the number of status rings: echo NUM_OF_STATUS_RINGS > num_rx_status_rings Run the following command to use extended RX status message for additional debug fields from HW: echo 0 > compressed_rx_status Run the following command to control the size of the TX status ring: echo TX_STATUS_RING_ORDER > tx_status_ring_order The status ring size will be 1 << tx_status_ring_order Run the following command to control the size of the RX status ring: echo RX_STATUS_RING_ORDER > rx_status_ring_order Due to HW constrains RX sring order should be bigger than RX ring order The status ring size will be 1 << rx_status_ring_order Run the following command to change the number of RX buffer IDs: echo RX_BUFF_ID_COUNT > rx_buff_id_count Signed-off-by: Gidon Studinski <gidons@codeaurora.org> Signed-off-by: Maya Erez <merez@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* wil6210: add support for enhanced DMA structuresGidon Studinski2018-07-021-17/+93
| | | | | | | | | | | | | | | | | | | | | | | | | In enhanced DMA the vrings are handled internally by the FW and are not exposed to the driver. Instead, the driver handles descriptor rings, which are mapped by the FW to vrings. The completions of the TX and RX descriptors are notified to the driver using status rings. Each status ring descriptor includes information of the completed descriptors and the ring id of their descriptor ring. This patch changes struct vring to generic wil_ring to allow its reuse for enhanced DMA descriptor rings and adds the descriptor and status rings specific descriptors. The vring debugfs entries have changed as follows: - dbg_vring_index has changed to dbg_ring_index - vrings has changed to rings - vring_idle_trsh has changed to ring_idle_trsh - vring_index has changed to ring_index Signed-off-by: Gidon Studinski <gidons@codeaurora.org> Signed-off-by: Maya Erez <merez@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
