The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and MIB_OBSS_AIRTIME from the radio and filling out cc_busy, cc_tx, cc_bss_rx and cc_rx respectively. busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this. Sometimes tx + rx is a bit higher than busy due to inaccurate accounting, so this patch recalculates numbers to make them more reasonable. Reported-By:

This reverts commit f17f4864 and adds the MT_DRV_AMSDU_OFFLOAD flag for MT7921 USB/SDIO The reverted commit significantly decreases performance when running a test where two MT7915 radios have 16 station vdevs each, configured for AC mode, and transmitting UDP traffic to AP. Co-developed-by:

In previous, we only allow user to configure tx antenna mask contiguously (e.g. 0x3, 0xf). This patch allows user to configure tx antenna mask interleavingly (e.g. 0x5, 0x8). By setting proper antenna mask and nss, user can prioritized the signal of different antennas, which helps to test their performance in normal mode. Signed-off-by:

A variant of mt7916 supports up to 3 tx/rx paths but with only 2 spatial streams. An example usage of the 3rd path is to server as an auxiliary for beamforming. In order to deal with this case, this patch reworks some parts to correctly use paths or streams. Signed-off-by:

Group 3 in RxD is disabled in monitor mode. We should use the group 5 in RxD instead to fix antenna signal way off issue, e.g we would see the incorrect antenna signal value in wireshark. On the other hand, Group 5 wouldn't be used in STA or AP mode, so the patch shouldn't cause any harm to those modes. Fixes: cbaa0a40 ("mt76: mt7921: fix up the monitor mode") Reported-by:

ieee80211_drop_unencrypted is called from ieee80211_rx_h_mesh_fwding and ieee80211_frame_allowed. Since ieee80211_rx_h_mesh_fwding can forward packets for other mesh nodes and is called earlier, it needs to check the decryptions status and if the packet is using the control protocol on its own, instead of deferring to the later call from ieee80211_frame_allowed. Because of that, ieee80211_drop_unencrypted has a mesh specific check that skips over the mesh header in order to check the payload protocol. This code is invalid when called from ieee80211_frame_allowed, since that happens after the 802.11->802.3 conversion. Fix this by moving the mesh specific check directly into ieee80211_rx_h_mesh_fwding. Signed-off-by:

This can be used to selectively disable feature flags for checksum offload, scatter/gather or GSO by changing vif->netdev_features. Removing features from vif->netdev_features does not affect the netdev features themselves, but instead fixes up skbs in the tx path so that the offloads are not needed in the driver. Aside from making it easier to deal with vif type based hardware limitations, this also makes it possible to optimize performance on hardware without native GSO support by declaring GSO support in hw->netdev_features and removing it from vif->netdev_features. This allows mac80211 to handle GSO segmentation after the sta lookup, but before itxq enqueue, thus reducing the number of unnecessary sta lookups, as well as some other per-packet processing.

When building with -Wstringop-overflow, GCC's KASAN implementation does not correctly perform bounds checking within some complex structures when faced with literal offsets, and can get very confused. For example, this warning is seen due to literal offsets into sturct ieee80211_hdr that may or may not be large enough: drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c: In function 'iwl_mvm_rx_mpdu_mq': drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c:2022:29: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=] 2022 | *qc &= ~IEEE80211_QOS_CTL_A_MSDU_PRESENT; In file included from drivers/net/wireless/intel/iwlwifi/mvm/fw-api.h:32, from drivers/net/wireless/intel/iwlwifi/mvm/sta.h:15, from drivers/net/wireless/intel/iwlwifi/mvm/mvm.h:27, from drivers/net/wireless/intel/iwlwifi/mvm/rxmq.c:10: drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/rx.h:559:16: note: at offset [78, 166] into destination object 'mpdu_len' of size 2 559 | __le16 mpdu_len; | ^~~~~~~~ Refactor ieee80211_get_qos_ctl() to avoid using literal offsets, requiring the creation of the actual structure that is described in the comments. Explicitly choose the desired offset, making the code more human-readable too. This is one of the last remaining warning to fix before enabling -Wstringop-overflow globally.

First, introduce struct rtw89_sub_entity for chanctx related stuffs. Second, add enum rtw89_sub_entity_idx to rtw89_vif for vif operation to access its/right chanctx stuffs after future multi-channel support. Besides, RTW89_SUB_ENTITY_0 is the default chanctx entry throughout driver, i.e. it's used for things which may not have a target chanctx yet. So, we need to ensure that RTW89_SUB_ENTITY_0 is always working. If there is at least one alive chanctx, then one of them must take RTW89_SUB_ENTITY_0. If no alive chanctx, RTW89_SUB_ENTITY_0 will be filled by rtw89_config_default_chandef(). Signed-off-by:

These MCC H2C(s) require to wait for MCC C2H to determine if the execution is successful. Through rtw89_wait_for_cond(), we make them wait for either a completion with data from MCC C2H handlers, which calls rtw89_complete_cond(), or timeout. Signed-off-by:

Process C2H(s) related to MCC (multi-channel concurrency). These handling, which either call rtw89_complete_cond() or show message in debug mode, can be considered atomic/lock-free. So, they should be safe to be processed directly after C2H pre-check in previous patch. Signed-off-by:

MCC (multi-channel concurrency) related H2Cs (host to chip commands) require to wait for C2H (chip to host events) responses to judge the execution result and data. We introduce helpers to assist this process. Besides, we would like the helpers to be generic for use in driver even outside of MCC H2C/C2H, so we make a independent patch for them. In the following, I describe the things first. ``` (A) C2H is generated by FW, and then transferred upto driver. Hence, driver cannot get it immediately without a bit waitting/blocking. For this, we choose to use wait_for_completion_*() instead of busy polling. (B) From the driver management perspective, a scenario, e.g. MCC, may have mulitple kind of H2C functions requiring this process to wait for corresponding C2Hs. But, the driver management flow uses mutex to protect each behavior. So, one scenario triggers one H2C function at one time. To avoid rampant instances of struct completion for each H2C function, we choose to use one struct completion with one condition flag for one scenario. (C) C2Hs, which H2Cs will be waitting for, cannot be ordered with driver management flow, i.e. cannot enqueue work to the same ordered workqueue and cannot lock by the same mutex, to prevent H2C side from getting no C2H responses. So, those C2Hs are parsed in interrupt context directly as done in previous commit. (D) Following (C), the above underline H2Cs and C2Hs will be handled in different contexts without sync. So, we use atomic_cmpxchg() to compare and change the condition in atomic. ``` So, we introduce struct rtw89_wait_info which combines struct completion and atomic_t. Then, the below are the descriptions for helper functions. * rtw89_wait_for_cond() to wait for a completion based on a condition. * rtw89_complete_cond() to complete a given condition and carry data. Each rtw89_wait_info instance independently determines the meaning of its waitting conditions. But, RTW89_WAIT_COND_IDLE (UINT_MAX) is reserved. Signed-off-by:

Before queuing C2H work, we check atomicity of the C2H's handler first now. If atomic or lock-free, handle it directly; otherwise, handle it with mutex in work as previous. This prepares for MAC MCC C2Hs which require to be processed directly. And, their handlers will be functions which can be considered atomic. Signed-off-by:

The `rtw89_mcc_info mcc` is only for RFK MCC stuffs instead of common MCC management info. Replace it with `rtw89_rfk_mcc_info rfk_mcc` to avoid confusion and reserve `struct rtw89_mcc_info mcc` for MCC management code. (No logic changes.) Signed-off-by:
