wifi: ath11k: fix peer resolution on rx path when peer_id=0

2026-06-01T15:39:41+00:00

[ Upstream commit 2a2451a34afdf563b3102d36a4b6cf335cf813e2 ] It has been observed that on certain chipsets a peer can be assigned peer_id=0. For reception of non-aggregated MPDUs this is fine as ath11k_dp_rx_h_find_peer() has a fallback case where it locates the peer based upon the source MAC address. On an aggregated link, the mpdu_start header is only populated by hardware on the first sub-MSDU. This causes the peer resolution to be skipped for the subsequent MSDUs and the encryption type of these frames to be set to an incorrect value, resulting in these MSDUs being dropped by ieee80211. ath11k_pci 0000:03:00.0: data rx skb 000000002f4b704d len 1534 peer xx:xx:xx:xx:xx:xx 0 ucast sn 3063 he160 rate_idx 9 vht_nss 2 freq 5240 band 1 flag 0x40d1a fcs-err 0 mic-err 0 amsdu-more 0 peer_id 0 first_msdu 1 last_msdu 0 ath11k_pci 0000:03:00.0: data rx skb 0000000038acd580 len 1534 peer (null) 0 ucast sn 3063 he160 rate_idx 9 vht_nss 2 freq 5240 band 1 flag 0x40d00 fcs-err 0 mic-err 0 amsdu-more 0 peer_id 0 first_msdu 0 last_msdu 1 Remove the null peer_id checks in ath11k_dp_rx_h_find_peer() and ath11k_hal_rx_parse_mon_status_tlv(), allowing peers with an assigned ID of 0 to be resolved.

wifi: ath11k: fix rssi station dump not updated in QCN9074

2026-06-01T15:39:41+00:00

[ Upstream commit 031ffa6c2cd305a57ccc6d610f2decd956b2e7f6 ] In QCN9074, station dump signal values display default value which is -95 dbm, since there is firmware header change for HAL_RX_MPDU_START between QCN9074 and IPQ8074 which cause wrong peer_id fetch from msdu. Fix this by updating hal_rx_mpdu_info with corresponding QCN9074 tlv format.

wifi: ath11k: add new hw ops for IPQ5018 to get rx dest ring hashmap

wifi: ath11k: remap ce register space for IPQ5018

[ Upstream commit b42b3678c91f3ca6e0888bf5a15c1e8678fd5f2d ] In IPQ5018 ce register space is moved out of wcss unlike ipq8074 or ipq6018 and the space is not contiguous, hence remap the CE registers to a new space to access them. Register read/write is modified to check if the register to be written falls in the CE register space and corresponding register is written.

wifi: ath11k: Trigger sta disconnect on hardware restart

2026-06-01T15:39:41+00:00

[ Upstream commit a018750a2cceaf4427c4ee3d9ce3e83a171d5bd6 ] Currently after the hardware restart triggered from the driver, the station interface connection remains intact, since a disconnect trigger is not sent to userspace. This can lead to a problem in targets where the wifi mac sequence is added by the firmware. After the target restart, its wifi mac sequence number gets reset to zero. Hence AP to which our device is connected will receive frames with a wifi mac sequence number jump to the past, thereby resulting in the AP dropping all these frames, until the frame arrives with a wifi mac sequence number which AP was expecting. To avoid such frame drops, its better to trigger a station disconnect upon target hardware restart which can be done with API ieee80211_reconfig_disconnect exposed to mac80211. The other targets are not affected by this change, since the hardware params flag is not set.
