WoWLAN is a feature which allows devices to be woken up from suspend state through WLAN events. When user enables WoWLAN feature and then let the device enter suspend state, WoWLAN firmware will be loaded by the driver and periodically monitors WiFi packets. Power consumption of WiFi chip will be reduced in this state. We now implement WoWLAN function in rtw8852ae and rtw8852ce chip. Currently supported WLAN events include receiving magic packet, rekey packet and deauth packet, and disconnecting from AP. Signed-off-by:

In this patch we define some H2C, which will be called during suspend flow, to enable WoWLAN function provided by WoWLAN firmware. These H2C includes keep alive used to send null packet to AP periodically to avoid being disconnected by AP, disconnect detection used to configure how we check if AP is offline, wake up control used to decide which WiFi events could trigger resume flow, and global control used to enable WoWLAN function.

For WoWLAN mode, we need to download WoWLAN firmware by calling fw_download(). Another, to disable/enable WiFi CPU is needed before calling fw_download. Since Firmware runs on WiFi CPU, it is intuitive to combine enable_cpu/disable_cpu functions into fw_download. Signed-off-by:

For WoWLAN mode, we only collect and send RF parameters to Firmware without writing RF registers. So we add one function to practice it. Signed-off-by:

Since firmware size is limited, we create variant firmwares for variant application areas. To help driver to know firmware's capabilities, firmware dynamic header is introduced to have more information, such as firmware features and firmware compile flags. Since this driver rtw89 only uses single one specific firmware at runtime, this patch is just to ignore this dynamic header, not actually use the content. This patch can be backward compatible, and no this kind of firmware is added to linux-firmware yet, so I can prepare this in advance. Signed-off-by:

In the event of a Tx hang it can be useful to read a variety of hardware registers to capture some state about why the transmit queue got stuck. Extend the ETHTOOL_GREGS dump provided by the ice driver with several CSR registers that provide such relevant information regarding the hardware Tx state. This enables capturing relevant data to enable debugging such a Tx hang. Signed-off-by:

Russell King says: ==================== net: mtk_eth_soc: improve PCS implementation As a result of invesigations from Frank Wunderlich, we know a lot more about the Mediatek "SGMII" PCS block, and can implement the PCS support correctly. This series achieves that, and Frank has tested the final result and reports that it works for him. The series could do with further testing by others, but I suspect that is unlikely to happen until it is merged based on past performances with this driver. Briefly, the patches in order: 1. Add a new helper to get the link timer duration in nanoseconds 2. Add definitions for the newly discovered registers and updates to bit definitions, including bitmasks for the BMCR, BMSR and two advertisement registers. 3. Remove unnecessary/unused error handling (functions always returning zero.) 4. Adding the missing pcs_get_state() implementation. 5. Converting the code to use regmap_update_bits() rather than open-coding read-modify-write sequences. 6. Adding out-of-band speed and duplex forcing for all non-inband modes not just the 802.3z link modes the code currently does. 7. Moving the release of the PHY power down to the main pcs_config() function. 8. Moving the interface speed selection to the main pcs_config() function. 9. Adding advertisement programming. 10. Adding correct link timer programming using the new helper in the first patch. 11. Adding support for 802.3z negotiation. There is one remaining issue - when configuring the PCS for in-band, for some reason the AN restart bit is always set. This should not be necessary, but requires further investigation with the hardware to find out whether it is really necessary. I suspect this was a work around for a previous poor implementation. ==================== Link: https://lore.kernel.org/r/Y1qDMw+DJLAJHT40@shell.armlinux.org.ukSigned-off-by: -

As a result of help from Frank Wunderlich to investigate and test, we now know how to program this PCS for in-band 802.3z negotiation. Add support for this by moving the contents of the two functions into the common mtk_pcs_config() function and adding the register settings for 802.3z negotiation. Signed-off-by:

Add support for forcing the link speed and duplex setting in the pcs_link_up() method for out of band modes, which will be useful when we finish converting the pcs_config() method. Until then, we still have to force duplex for 802.3z modes to work correctly. Signed-off-by:

==================== pull-request: wireless-next-2022-10-28 First set of patches v6.2. mac80211 refactoring continues for Wi-Fi 7. All mac80211 driver are now converted to use internal TX queues, this might cause some regressions so we wanted to do this early in the cycle. Note: wireless tree was merged[1] to wireless-next to avoid some conflicts with mac80211 patches between the trees. Unfortunately there are still two smaller conflicts in net/mac80211/util.c which Stephen also reported[2]. In the first conflict initialise scratch_len to "params->scratch_len ?: 3 * params->len" (note number 3, not 2!) and in the second conflict take the version which uses elems->scratch_pos.

During firmware recovery, the monitor interface is not getting created in the driver and firmware since the respective flags are not updated properly. So after firmware recovery is successful, when monitor interface is brought down manually, firmware assertion is observed, since we are trying to bring down the interface which is not yet created in the firmware. Fix this by updating the monitor flags properly per phy#, during firmware recovery. Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 Signed-off-by:

Mubashir Adnan Qureshi says: ==================== net: Add PLB functionality to TCP This patch series adds PLB (Protective Load Balancing) to TCP and hooks it up to DCTCP. PLB is disabled by default and can be enabled using relevant sysctls and support from underlying CC. PLB (Protective Load Balancing) is a host based mechanism for load balancing across switch links. It leverages congestion signals(e.g. ECN) from transport layer to randomly change the path of the connection experiencing congestion. PLB changes the path of the connection by changing the outgoing IPv6 flow label for IPv6 connections (implemented in Linux by calling sk_rethink_txhash()). Because of this implementation mechanism, PLB can currently only work for IPv6 traffic.
