To fix possibly the race to access register between the WiFi reset and the other context that is caused by explicitly cancelling ps_work and wake_work to break PM_STATE consistency. Deep sleep would cause the hardware into the inactive state, so we forcely put device drv_own state before we start to reset. The patch also ignore the reset request when the procedure is in progress to avoid the consecutive WiFi resets. localhost ~ # [ 2932.073966] SError Interrupt on CPU7, code 0xbe000011 [ 2932.073967] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073968] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073968] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073969] pstate: 80400089 (Nzcv daIf +PAN -UAO) [ 2932.073969] pc : el1_irq+0x78/0x180 [ 2932.073970] lr : mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073970] sp : ffffffc01142bad0 [ 2932.073970] x29: ffffffc01142bc00 x28: ffffff8f96fb1e00 [ 2932.073971] x27: ffffffd2cdc12138 x26: ffffffd2cdaeb018 [ 2932.073972] x25: 0000000000000000 x24: ffffff8fa8e14c08 [ 2932.073973] x23: 0000000080c00009 x22: ffffffd2a5603918 [ 2932.073974] x21: ffffffc01142bc10 x20: 0000007fffffffff [ 2932.073975] x19: 0000000000000000 x18: 0000000000000400 [ 2932.073975] x17: 0000000000000400 x16: ffffffd2cd2b87dc [ 2932.073976] x15: 0000000000000000 x14: 0000000000000000 [ 2932.073977] x13: 0000000000000001 x12: 0000000000000001 [ 2932.073978] x11: 0000000000000001 x10: 000000000010e000 [ 2932.073978] x9 : 0000000000000000 x8 : ffffffc013921404 [ 2932.073979] x7 : 000000b2b5593519 x6 : 0000000000300000 [ 2932.073980] x5 : 0000000000000000 x4 : ffffffc01142bbc8 [ 2932.073980] x3 : 00000000000001f0 x2 : 0000000000000000 [ 2932.073981] x1 : 0000000000021404 x0 : ffffff8fa8e12300 [ 2932.073982] Kernel panic - not syncing: Asynchronous SError Interrupt [ 2932.073983] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073983] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073984] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073984] Call trace: [ 2932.073985] dump_backtrace+0x0/0x14c [ 2932.073985] show_stack+0x20/0x2c [ 2932.073985] dump_stack+0xa0/0xf8 [ 2932.073986] panic+0x154/0x360 [ 2932.073986] test_taint+0x0/0x44 [ 2932.073986] arm64_serror_panic+0x78/0x84 [ 2932.073987] do_serror+0x0/0x118 [ 2932.073987] do_serror+0xa4/0x118 [ 2932.073987] el1_error+0x84/0xf8 [ 2932.073988] el1_irq+0x78/0x180 [ 2932.073988] mt76_mmio_rr+0x30/0xf0 [mt76] [ 2932.073988] mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073989] mt7921_rmw+0x4c/0x5c [mt7921e] [ 2932.073989] mt7921_configure_filter+0x138/0x160 [mt7921e] [ 2932.073990] ieee80211_configure_filter+0x2f0/0x3e0 [mac80211] [ 2932.073990] ieee80211_reconfig_filter+0x1c/0x28 [mac80211] [ 2932.073990] process_one_work+0x208/0x3c8 [ 2932.073991] worker_thread+0x23c/0x3e8 [ 2932.073991] kthread+0x140/0x17c [ 2932.073992] ret_from_fork+0x10/0x18 [ 2932.074071] SMP: stopping secondary CPUs [ 2932.074071] Kernel Offset: 0x12bc800000 from 0xffffffc010000000 [ 2932.074072] PHYS_OFFSET: 0xfffffff180000000 [ 2932.074072] CPU features: 0x080026,2a80aa18 [ 2932.074072] Memory Limit: none Co-developed-by:

Add runtime configuration for bitrate mask. This update firmware rate control to add a boundary on top of table to limit the rate selection for each peer, so when user set bitrates vht-mcs-5 1:9, which actually means nss = 1 mcs = 0~9. This only applies to data frames as for other mgmt, mcast, bcast still use legacy rates as it is. Note that driver does not support GI configuration. Example: iw dev wlan0 set bitrates vht-mcs-5 1:9 he-mcs-5 2:7 iw dev wlan0 set bitrates legacy-5 6 he-mcs-5 2:0-11 Signed-off-by:

Karsten Graul says: ==================== net/smc: Add SMC statistic support Please apply the following patch series for smc to netdev's net-next tree. This v2 is a resend of the code contained in v1 but with an updated cover letter to describe why we have chosen to use the generic netlink mechanism to access the smc protocol's statistic data. The patchset adds statistic support to the SMC protocol. Per-cpu variables are used to collect the statistic information for better performance and for reducing concurrency pitfalls. The code that is collecting statistic data is implemented in macros to increase code reuse and readability. The generic netlink mechanism in SMC is extended to provide the collected statistics to userspace. Network namespace awareness is also part of the statistics implementation. SMC is a protocol interacting with PCI devices (like RoCE Cards) and runs on top of the TCP protocol. As SMC is a network protocol and not an ethernet device driver, we decided to use the generic netlink interface. This should be comparable to what other protocols in the net subsystem like tipc, ncsi, ieee802154 or tcp, et al, do. There is already an established internal generic netlink interface mechanism in SMC which is used to collect SMC Protocol internal information. This patchset extends that existing mechanism. ==================== Signed-off-by: -
