The logic here is rather convoluted - we cannot get here with lq_sta being NULL as mac80211 will (no longer) call us like that, and since I removed the rate_control_send_low() call in this function there's no longer any point in setting priv_sta to NULL either. So the only thing that remains to check is if we have actually initialized our lq_sta->drv pointer, and exit if we didn't in which case we'll use the data mac80211 already set up for the low rate usage.

Instead of passing the full TPE elements, in all their glory and mixed up data formats for HE backward compatibility, parse them fully into the right values, and pass that to the drivers. Also introduce proper validation already in mac80211, so that drivers don't need to do it, and parse the EHT portions. The code now passes the values in the right order according to the channel used by an interface, which could also be a subset of the data advertised by the AP, if we couldn't connect with the full bandwidth (for whatever reason.) Also add kunit tests for the more complicated bits of it. Reviewed-by:

The chanctx can be shared, but it seems like the TPE values for this vif should only reflect the channel that the vif uses, which is captured in bss_conf->chanreq.oper rather than the chanctx. Use that when calculating defaults, a similar issue is where the data from the AP is processed, but I'm moving that to mac80211. Acked-by:

The define IEEE80211_MAX_NUM_PWR_LEVEL doesn't make much sense. Yes, that table has a maximum value of 8, and the table will actually remain that way, but EHT introduced a way to encode more levels for 320 MHz channels. Remove IEEE80211_MAX_NUM_PWR_LEVEL and, for ath11k being the only user, add ATH11K_NUM_PWR_LEVELS, where it makes sense since it cannot support 320 MHz channels. Acked-by:

When changing the interface type we also need to update the bss_num, the driver private data is searched based on a unique (bss_type, bss_num) tuple, therefore every time bss_type changes, bss_num must also change. This fixes for example an issue in which, after the mode changed, a wireless scan on the changed interface would not finish, leading to repeated -EBUSY messages to userspace when other scan requests were sent.

The default netdev interface exposed by WILC1000 is registered at probe, but the chip mac address is not known until ndo_open, which will load and start chip firmware and then retrieve stored MAC address from it. As a consequence, the interface has uninitialized value (00:00:00:00:00) until a user brings up the interface. Fix MAC address at probe by setting the following steps: - at probe, read MAC address directly from fuse - whenever a new netdevice is created, apply saved mac address (which can be a user-provided address, or the eFuse Mac address if no address has been passed by user) - whenever an interface is brought up for the first time (and so the firmware is loaded and started), enforce netdevice mac address to the chip (in case user has changed it) Reported-by:

In order to be able to read raw registers (eg the nv mac address) in wilc1000 during probe before the firmware is loaded and running, we need to run the basic sdio functions initialization, but then we also need to properly deinitialize those right after, to preserve the current driver behavior (keeping the chip idle/unconfigured until the corresponding interface is brought up). Calling wilc_sdio_deinit in its current form is not enough because it merely resets an internal flag. Implement a deinit sequence which symmetrically reset all steps performed in wilc_sdio_init (only for parts activating/deactivating features, for the sake of simplicity, let's ignore blocks size configuration reset) Signed-off-by:

wilc driver currently reads and sets mac address by firmware calls. It means that we can not access mac address if no interface has been brought up (so firmware is up and running).

SDIO/SPI probes functions automatically add a default wlan interface on top of registered wiphy, through wilc_cfg80211_init which in turn calls wilc_netdev_ifc_init. However, bus is still not fully initialized when we register corresponding net device (for example we still miss some private driver data pointers), which for example makes it impossible to retrieve MAC address from chip (which is supposed to be set on net device before its registration) before registering net device. More generally, net device registration should not be done until driver has fully initialized everything and is ready to handle any operation on the net device. Prevent net device from being registered so early by doing it at the end of probe functions. Apply this logic to both sdio and spi buses. Signed-off-by:

net device registration is currently done in wilc_netdev_ifc_init but other initialization operations are still done after this registration. Since net device is assumed to be usable right after registration, it should be the very last step of initialization. Move netdev registration at the very end of wilc_netdev_ifc_init to let this function completely initialize netdevice before registering it. Signed-off-by:

Merge tag 'wireless-next-2024-05-08' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next Kalle Valo says: ==================== wireless-next patches for v6.10 The third, and most likely the last, "new features" pull request for v6.10 with changes both in stack and in drivers. In ath12k and rtw89 we disabled Wireless Extensions just like with iwlwifi earlier. Wi-Fi 7 devices will not support Wireless Extensions (WEXT) anymore so if someone is still using the legacy WEXT interface it's time to switch to nl80211 now! We merged wireless into wireless-next as we decided not to send a wireless pull request to v6.9 this late in the cycle. Also an immutable branch with MHI subsystem was merged to get ath11k and ath12k hibernation working.

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.
