The CCK TX setting when switch channel will fix the CCK to path A only, so if the antenna is configured to path B (e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK packets can never be delivered to the air if only path B is connected with an antenna (it can possibly be transmitted through path A, but as path B is configured, the expected behavior is incorrect). This can also solve the racing issue of CCK TX setting between driver and firmware. The CCK TX setting in driver should be removed. Otherwise, the CCK TX setting would be wrong when the racing occurs. Fixes: 297bcf82 ("rtw88: add support for set/get antennas") Signed-off-by:

Connecting to an AP with WPA2 security may fail. The IQK and the EAPOL 4-way handshake may overlap because the driver does IQK right after assoc success. For 802.11n devices, the IQK is done in the driver and it could require more than 100ms to complete. During IQK, any TX/RX events are paused. So if the EAPOL 4-way handshake started before IQK finished, then the 1/4 and 2/4 part of the handshake could be dropped. The AP will then issue deauth with reason IEEE8021X_FAILED (23). To resolve this, move IQK routine into managed TX prepare (ieee80211_ops::mgd_prepare_tx()). The callback is called before the managed frames (auth/assoc) are sent. This will make sure that the IQK is completed before the handshake starts. But don't do IQK during scanning because doing it on each channel will take too long. For 802.11ac devices, the IQK is done in firmware and it takes less time to complete. Therefore we don't see a failure during the EAPOL 4-way handshake. But it is still worth moving the IQK into ieee80211_ops::mgd_prepare_tx(). Fixes: f5df1a8b ("rtw88: 8723d: Add 8723DE to Kconfig and Makefile") Tested-by:

Coex mechanism used to make BT have higher priority and more time to transfer data when BT inquiry-page, which leads to poor WiFi performance. Should take WiFi traffic into consideration. If the WiFi is having heavy traffic, use another parameter to make sure WiFi has more chance to TX/RX, while guarantee the priority of BT for inquiry. If the WiFi isn't busy (connected or not), set proper parameter to fix originals. Fixes: f5df1a8b ("rtw88: 8723d: Add 8723DE to Kconfig and Makefile") Tested-by:

Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43legacy did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43legacy will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers. Signed-off-by:

This reverts commit 07d0f553. For rtw88 driver, the SDIO is going to be supported, so there is no need to remove the SDIO related power sequence settings. And while the power sequence parser will pass in the mask of the HCI, the SDIO part will not be used to set registers accordingly. Moreover, the power sequence table is released as a whole package, so the next time if we are going to update, the SDIO settings will be overwritten. So, revert this now. Signed-off-by:

This patch adds a field to the tls rx offload context which enables drivers to force a send_resync call. This field can be used by drivers to request a resync at the next possible tls record. It is beneficial for hardware that provides the resync sequence number asynchronously. In such cases, the packet that triggered the resync does not contain the information required for a resync. Instead, the driver requests resync for all the following TLS record until the asynchronous notification with the resync request TCP sequence arrives. A following series for mlx5e ConnectX-6DX TLS RX offload support will use this mechanism. Signed-off-by:

Patch 1~3 are preparation for their following patches, especially patch 2 and patch 3 add a few tracepoints so that we can observe the whole lifetime of qdisc's. Patch 4 and patch 5 are the ones do the actual work. Please find more details in each patch description.

Resetting old qdisc on dev_queue->qdisc_sleeping in dev_qdisc_reset() is redundant, because this qdisc, even if not same with dev_queue->qdisc, is reset via qdisc_put() right after calling dev_graft_qdisc() when hitting refcnt 0. This is very easy to observe with qdisc_reset() tracepoint and stack traces. Reported-by:

Except for sch_mq and sch_mqprio, each dev queue points to the same root qdisc, so when we reset the dev queues with netdev_for_each_tx_queue() we end up resetting the same instance of the root qdisc for multiple times. Avoid this by checking the __QDISC_STATE_DEACTIVATED bit in each iteration, so for sch_mq/sch_mqprio, we still reset all of them like before, for the rest, we only reset it once. Reported-by:
