At least on BCM4387, the D11 cores are held in reset on cold startup and firmware expects to release reset itself. Just assert reset here and let firmware deassert it.

2023-02-22wifi: rtw89: refine FW feature judgement on packet dropZong-Zhe Yang
The newer chips use the newer firmware branches, e.g. v027, v029. And, those firmware branches are supposed to support packet drop when they are just branched out. The initial firmware branch used by each chip is as below. * 8852A: v009 * 8852C: v027 * 8852B: v027 So, only 8852A may use firmware which doesn't support packet drop at runtime. To save trivial positive listing in firmware feature table, we change to reverse judgment.

Since 6 GHz band has around 60 channels and more strict rules for active probing. Reduced neighbor report can be used to reduce the channels we scan and get specific target BSS info to probe for. Declare flag WIPHY_FLAG_SPLIT_SCAN_6GHZ so the scan request could be divided into two portions: legacy bands and 6 GHz bands. So RNR information from legacy bands could later be used when 6 GHz scan. When the scan flag NL80211_SCAN_FLAG_COLOCATED_6GHZ is set, cfg80211 will pass down a reduced channel set which contains PSCs and non-PSC with RNR info received in the 2 GHz/5 GHz band. This reduces the scan duration by allowing us to only scan for channels in which APs are currently operating.

2023-02-20net/mlx5e: TC, Set CT miss to the specific ct action instancePaul Blakey
Currently, CT misses restore the missed chain on the tc skb extension so tc will continue from the relevant chain. Instead, restore the CT action's miss cookie on the extension, which will instruct tc to continue from the this specific CT action instance on the relevant filter's action list. Map the CT action's miss_cookie to a new miss object (ACT_MISS), and use this miss mapping instead of the current chain miss object (CHAIN_MISS) for CT action misses. To restore this new miss mapping value, add a RX restore rule for each such mapping value.

2023-02-20net/mlx4_en: Introduce flexible array to silence overflow warningKees Cook
The call "skb_copy_from_linear_data(skb, inl + 1, spc)" triggers a FORTIFY memcpy() warning on ppc64 platform: In function ‘fortify_memcpy_chk’, inlined from ‘skb_copy_from_linear_data’ at ./include/linux/skbuff.h:4029:2, inlined from ‘build_inline_wqe’ at drivers/net/ethernet/mellanox/mlx4/en_tx.c:722:4, inlined from ‘mlx4_en_xmit’ at drivers/net/ethernet/mellanox/mlx4/en_tx.c:1066:3: ./include/linux/fortify-string.h:513:25: error: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] 513 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Same behaviour on x86 you can get if you use "__always_inline" instead of "inline" for skb_copy_from_linear_data() in skbuff.h The call here copies data into inlined tx destricptor, which has 104 bytes (MAX_INLINE) space for data payload. In this case "spc" is known in compile-time but the destination is used with hidden knowledge (real structure of destination is different from that the compiler can see). That cause the fortify warning because compiler can check bounds, but the real bounds are different. "spc" can't be bigger than 64 bytes (MLX4_INLINE_ALIGN), so the data can always fit into inlined tx descriptor. The fact that "inl" points into inlined tx descriptor is determined earlier in mlx4_en_xmit(). Avoid confusing the compiler with "inl + 1" constructions to get to past the inl header by introducing a flexible array "data" to the struct so that the compiler can see that we are not dealing with an array of inl structs, but rather, arbitrary data following the structure. There are no changes to the structure layout reported by pahole, and the resulting machine code is actually smaller.

2023-02-20net: bcmgenet: Support wake-up from s2idleFlorian Fainelli
When we suspend into s2idle we also need to enable the interrupt line that generates the MPD and HFB interrupts towards the host CPU interrupt controller (typically the ARM GIC or MIPS L1) to make it exit s2idle. When we suspend into other modes such as "standby" or "mem" we engage a power management state machine which will gate off the CPU L1 controller (priv->irq0) and ungate the side band wake-up interrupt (priv->wol_irq). It is safe to have both enabled as wake-up sources because they are mutually exclusive given any suspend mode. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
