2025-05-12net: cadence: macb: Fix a possible deadlock in macb_halt_tx.Mathieu Othacehe
There is a situation where after THALT is set high, TGO stays high as well. Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock. That deadlock was noticed on a sama5d4 device that stayed locked for days. Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.

2025-05-12net: ixp4xx_eth: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()Vladimir Oltean
New timestamping API was introduced in commit 66f7223039c0 ("net: add NDOs for configuring hardware timestamping") from kernel v6.6. It is time to convert the intel ixp4xx ethernet driver to the new API, so that the ndo_eth_ioctl() path can be removed completely. hwtstamp_get() and hwtstamp_set() are only called if netif_running() when the code path is engaged through the legacy ioctl. As I don't want to make an unnecessary functional change which I can't test, preserve that restriction when going through the new operations. When cpu_is_ixp46x() is false, the execution of SIOCGHWTSTAMP and SIOCSHWTSTAMP falls through to phy_mii_ioctl(), which may process it in case of a timestamping PHY, or may return -EOPNOTSUPP. In the new API, the core handles timestamping PHYs directly and does not call the netdev driver, so just return -EOPNOTSUPP directly for equivalent logic. A gratuitous change I chose to do anyway is prefixing hwtstamp_get() and hwtstamp_set() with the driver name, ipx4xx. This reflects modern coding sensibilities, and we are touching the involved lines anyway. The remainder of eth_ioctl() is exactly equivalent to phy_do_ioctl_running(), so use that.

2025-05-10wifi: iwlwifi: cfg: add ucode API min/max to MAC configJohannes Berg
In some older devices, the min/max firmware API supported by the driver depends on the specific device, when sharing the the same MAC (config). For most newer devices, it really is dependent on the MAC instead, since the firmware was frozen for certain MAC types. However, in the future we expect also freezes for RF types there. To handle this most generally, add an API min/max to the MAC config and then use the narrowest range prescribed by both, if set. For the newer MACs since 9000, move the configuration, there was only a freeze on MAC+RF lines so far.

2025-05-10wifi: rtw89: add MLO track for MLSR switch decisionPo-Hao Huang
Add MLSR switch mechanism based on tracking RSSI. Switch to a 2 GHz link (if any) when average RSSI is lower than threshold -53. And, switch out from a 2 GHz link when average RSSI is larger than threshold -38. The sequence of MLSR switch handling is like the following. 1. initialize target link and configure to PS mode 2. configure current designated link to PS mode 3. configure target link to non-PS mode 4. deinitialize currently active links except target link The above flow also implies that target link becomes new designated link.

2025-05-10wifi: rtw89: chan: re-calculate MLO DBCC mode during setting channelZong-Zhe Yang
Wi-Fi 7 chips have dual HW bands. After impending MLO support, they can work with HW-[0] / HW-[1] / HW-[0,1] according to active links. So, during setting channel, also re-calculate the MLO DBCC mode flag. Then, leaf chip functions of setting channel can configure with HWs based on current case. Besides, tweak the initial and idle MLO DBCC mode of Wi-Fi 7 chips to MLO_1_PLUS_1_1RF to work with dual HW bands. And, after disconnecting, due to no active links, MLO DBCC mode will re-calculate to idle case, i.e. MLO_1_PLUS_1_1RF.

For data packets that can be sent on any band, fill in main mac_id and let HW decide. For packets that we wish to transmit on specific band, fill in sw_mld field so HW would only send it on that band. Main mac_id is the corresponding mac_id on band 0.

2025-05-10wifi: rtw88: Handle RTL8723D(S) with blank efuseBitterblue Smith
Some users have RTL8723DS chips with nearly blank efuse. Currently these chips cannot connect when using rtw88, but they do work using the old out-of-tree driver. Use reasonable default values for TX power, antenna configuration, and crystal cap if the chip's efuse is missing these things. RTL8723D can use the same default values as RTL8703B, so simply move the code from rtl8703b_read_efuse() to the shared function __rtl8723x_read_efuse().
