PCI PHY EQ value is missing after card off/on, so update the value after device resume. The original commit only updates once at probe stage, which could lead problem after suspend/resume. The logic should be read a value from one register and write to another register with a mask to avoid affecting unrelated bits.

There is a length limit on the commands we send to firmware, so dividing to two commands is sometimes required when scanning. When aborting scan, we should not send second scan command to firmware after the first one is finished. This could cause some unexpected errors when we cannot receive firmware events (e.g. in suspend). Another case is scan happens before suspending, ieee80211_do_stop() is called to abort scan and driver indicate scan completion by ieee80211_scan_completed(), which queues event to scan work. But scan work might be late to execute after ieee80211_do_stop(). To correct this, driver indicates ieee80211_scan_completed() before returning, so that ieee80211_do_stop() can flush scan work properly.

On 802.11be chips, to consider MLO, HW doesn't design number of support mac_id as large as before. And, it might be various according to chip. For example, old chips support mac_id up to 128, but RTL8922a only supports mac_id up to 32. Besides, the mac_id acquiring function will be extended when impending MLO support. Signed-off-by:

For impending MLO support, we drop bss_info_changed callback ahead and switch to register new callbacks, vif_cfg_changed and link_info_changed, which are introduced by mac80211 for multi-link point of view. Besides, there is a place where we called ieee80211_find_sta() under station mode. To work on both non-MLD and MLD connection, we should call ieee80211_find_sta() with vif->cfg.ap_addr.

In original code architecture, sec CAM is a component of addr CAM. Hence, sec CAM could not be shared. After MLO, each link has its own addr CAM. However, one MLD PTK takes only one sec CAM but it needs to work on multiple links' addr CAMs. So, we now manage sec CAMs in global pool, and each of them is not bound to a single addr CAM now. before: +-----------------+ +--------------------+ | rtw89_{vif/sta} | ... | ieee80211_key_conf | +-----------------+ +--------------------+ ^ | V | hw_key_idx | | | V | +-- +----------+ addr_cam::key_idx | \ +---------+ | addr_cam |<>---------------------| |-------| sec_cam | +----------+ | / +---------+ +-- after: +----------------------+ +--------------------+ | rtw89_{vif/sta}_link | ... | ieee80211_key_conf | +----------------------+ +--------------------+ ^ | V | hw_key_idx | | | V | --+ +---------+ | +---------+ / | sec_cam_idx | global | | | sec_cam |-------| |----------------<>| sec_cam | | +---------+ \ | | pool | | ^ --+ +---------+ | | | (*) | +----------+ | | addr_cam |-------------+ +----------+ Signed-off-by: -

When there is beacon loss, for example due to unrelated Bluetooth devices transmitting music nearby, the wifi connection dies soon after the first beacon loss message: Apr 28 20:47:14 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:15 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:24 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:25 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 Apr 28 20:47:34 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-BEACON-LOSS Apr 28 20:47:35 ideapad2 wpa_supplicant[1161]: wlp3s0f3u4: CTRL-EVENT-DISCONNECTED bssid=... reason=4 locally_generated=1 When the beacon loss happens, mac80211 makes rtw88 transmit a QOS NULL frame and asks to confirm the ACK status. Even though rtw88 confirms to mac80211 that the QOS NULL was transmitted successfully, the connection still dies. This is because rtw88 is handing the QOS NULL back to mac80211 with skb->data pointing to the headroom (the TX descriptor) instead of ieee80211_hdr. Fix the disconnection by moving skb->data to the correct position before ieee80211_tx_status_irqsafe().

Run tools/testing/selftest/net/csum.c as part of drv-net. This binary covers multiple scenarios, based on arguments given, for both IPv4 and IPv6: - Accept UDP correct checksum - Detect UDP invalid checksum - Accept TCP correct checksum - Detect TCP invalid checksum - Transmit UDP: basic checksum offload - Transmit UDP: zero checksum conversion The test direction is reversed between receive and transmit tests, so that the NIC under test is always the local machine. In total this adds up to 12 testcases, with more to follow. For conciseness, I replaced individual functions with a function factory. Also detect hardware offload feature availability using Ethtool netlink and skip tests when either feature is off. This need may be common for offload feature tests and eventually deserving of a thin wrapper in lib.py. Missing are the PF_PACKET based send tests ('-P'). These use virtio_net_hdr to program hardware checksum offload. Which requires looking up the local MAC address and (harder) the MAC of the next hop. I'll have to give it some though how to do that robustly and where that code would belong.

Currently the ipq806x dwmac driver is almost always used attached to the CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii". Some device came up with a special configuration where the PHY is directly attached to the GMAC port and in those case phy-mode needs to be set to "rgmii-id" to make the PHY correctly work and receive packets. Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id" (or variants) mode is set, the mode is rejected and probe fails. Add support also for these phy-modes to correctly setup PHYs that requires delay applied to tx/rx. Signed-off-by:

Enhance the error reporting mechanism in the switchdev framework to provide more informative and user-friendly error messages. Following feedback from users struggling to understand the implications of error messages like "failed (err=-28) to add object (id=2)", this update aims to clarify what operation failed and how this might impact the system or network. With this change, error messages now include a description of the failed operation, the specific object involved, and a brief explanation of the potential impact on the system. This approach helps administrators and developers better understand the context and severity of errors, facilitating quicker and more effective troubleshooting. Example of the improved logging: [ 70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast Database entry (object id=2) with error: -ENOSPC (-28). [ 70.516446] Failure in updating the port's Multicast Database could lead to multicast forwarding issues. [ 70.516446] Current HW/SW setup lacks sufficient resources. This comprehensive update includes handling for a range of switchdev object IDs, ensuring that most operations within the switchdev framework benefit from clearer error reporting.

Introduce a tracepoint for icmp_send, which can help users to get more detail information conveniently when icmp abnormal events happen. 1. Giving an usecase example: ============================= When an application experiences packet loss due to an unreachable UDP destination port, the kernel will send an exception message through the icmp_send function. By adding a trace point for icmp_send, developers or system administrators can obtain detailed information about the UDP packet loss, including the type, code, source address, destination address, source port, and destination port. This facilitates the trouble-shooting of UDP packet loss issues especially for those network-service applications. 2. Operation Instructions: ========================== Switch to the tracing directory. cd /sys/kernel/tracing Filter for destination port unreachable. echo "type==3 && code==3" > events/icmp/icmp_send/filter Enable trace event. echo 1 > events/icmp/icmp_send/enable 3.

Microchip KSZ and LAN variants do not have per port DSCP priority configuration. Instead there is a global DSCP mapping table. This patch provides write access to this global DSCP map. In case entry is "deleted", we map corresponding DSCP entry to a best effort prio, which is expected to be the default priority for all untagged traffic. Signed-off-by:
