In typical cases, there's no need to pass both the maxattr and the policy array pointer, as the maxattr should just be ARRAY_SIZE(policy) - 1. Therefore, to be less error prone, just remove the maxattr argument from the default macros and deduce the size accordingly. Leave the original macros with a leading underscore to use here and in case somebody needs to pass a policy pointer where the policy isn't declared in the same place and thus ARRAY_SIZE() cannot be used.

WoL handling for the RTL8168 family is a little bit tricky because of different types of broken BIOS and/or chip quirks. Two known issues: 1. Network properly resumes from suspend only if WoL is enabled in the chip. 2. Some notebooks wake up immediately if system is suspended and network device is wakeup-enabled. Few patches tried to deal with this: 7edf6d31 ("r8169: disable WOL per default") 18041b52 ("r8169: restore previous behavior to accept BIOS WoL settings") Currently we have the situation that the chip WoL settings as set by the BIOS are respected (to prevent issue 1), but the device doesn't get wakeup-enabled (to prevent issue 2). This leads to another issue: If systemd is told to set WoL it first checks whether the requested settings are active already (and does nothing if yes). Due to the chip WoL flags being set properly systemd assumes that WoL is configured properly in our case. Result is that device doesn't get wakeup-enabled and WoL doesn't work (until it's set e.g. by ethtool). This patch now: - leaves the chip WoL settings as is (to prevent issue 1) - keeps the behavior to not wakeup-enable the device initially (to prevent issue 2) - In addition we report WoL as being disabled in get_wol, matching that device isn't wakeup-enabled. If systemd is told to enable WoL, it will therefore detect that it has to do something and will call set_wol. Of course the user still has the option to override this with e.g. ethtool. v2: - Don't just exclude __rtl8169_get_wol() from compiling, remove it. v3: - adjust commit message Signed-off-by:

When the driver is unloading, if a global reset occurs, unmap_ring_from_vector() in the hns3_nic_uninit_vector_data() will fail, and hns3_nic_uninit_vector_data() just return.

Greg Ungerer says: ==================== net: dsa: mt7530: support MT7530 in the MT7621 SoC This is the fourth version of a patch series supporting the MT7530 switch as used in the MediaTek MT7621 SoC. Unlike the MediaTek MT7623 the MT7621 is built around a dual core MIPS CPU architecture. But inside it uses basically the same 7530 switch. This series resolves all issues I had with previous versions, and I can now reliably use the driver on a 7621 SoC platform. These patches were generated against linux-5.0-rc4. The first patch enables support for the existing kernel mediatek ethernet driver on the MT7621 SoC. This support is from Bjørn Mork, with an update and fix by me. Using this driver fixed a number of problems I had (TX checksums, large RX packet drop) over the staging driver (drivers/staging/mt7621-eth). Patch 2 modifies the mt7530 DSA driver to support the 7530 switch as implemented in the Mediatek MT7621 SoC. The last patch updates the devicetree bindings to reflect the new support in the mt7530 driver. There is no real dependencies between the patches, so they can be taken independantly. Creating a new binding for the MT7621 seems like the only viable approach to distinguish between a stand alone 7530 switch, the silicon module in the MT7623 SoC and the silicon in the MT7621. Certainly the 7530 ID register in the MT7623 and MT7621 returns the same value, "0x7530001". Looking at the mt7530.c DSA driver it might make some sense to convert the existing "mediatek,mcm" binding to something like "mediatek,mt7623" to be consistent with this new MT7621 support. As far as I can tell this is the intention of this binding. ==================== Signed-off-by: -

The MediaTek MT7621 SoC device contains a 7530 switch, and the existing linux kernel 7530 DSA switch driver can be used with it. The bulk of the changes required stem from the 7621 having different regulator and pad setup. The existing setup of these in the 7530 driver appears to be very specific to its implemtation in the Mediatek 7623 SoC. (Not entirely surprising given the 7623 is a quad core ARM based SoC, and the 7621 is a dual core, dual thread MIPS based SoC). Create a new devicetree type, "mediatek,mt7621", to support the 7530 switch in the 7621 SoC. There appears to be no usable ID register to distinguish it from a 7530 in other hardware at runtime. This is used to carry out the appropriate configuration and setup. Signed-off-by:

The Mediatek MT7621 SoC contains the same ethernet hardware module as used on a number of other MediaTek SoC parts. There are some minor differences to deal with but we can use the same driver to support them all. This patch is based on work by Bjørn Mork <bjorn@mork.no>, and his original patch is at: https://github.com/bmork/LEDE/commit/3293bc63f5461ca1eb0bbc4ed90145335e7e3404 There is an additional compatible devicetree type added, and the primary change to the code required is to support a single interrupt (for both RX and TX interrupts).

Ido Schimmel says: ==================== mlxsw: spectrum_acl: Include delta bits into hashtable key The Spectrum-2 ASIC allows multiple rules to use the same mask provided that the difference between their masks is small enough (up to 8 consecutive delta bits). A more detailed explanation is provided in merge commit 756cd366 ("Merge branch 'mlxsw-Introduce-algorithmic-TCAM-support'"). These delta bits are part of the rule's key and therefore rules that only differ in their delta bits can be inserted with the same A-TCAM mask. In case two rules share the same key and only differ in their priority, then the second will spill to the C-TCAM. Current code does not take the delta bits into account when checking for duplicate rules, which leads to unnecessary spillage to the C-TCAM. This may result in reduced scale and performance. Patch #1 includes the delta bits in the rule's key to avoid the above mentioned problem. Patch #2 adds a tracepoint when a rule is inserted into the C-TCAM. Patches #3-#5 add test cases to make sure unnecessary spillage into the C-TCAM does not occur. ==================== Signed-off-by:

Currently only ERP mask masked bits in key are considered for the hashtable key. That leads to false negative collisions and fallbacks to C-TCAM in case two keys differ only in delta bits. Fix this by taking full encoded key as a hashtable key, including delta bits. Reported-by:

For one-to-many style sockets, often a socket option will pass a structure that includes an assoc_id field. This field can be filled with the association identifier of a particular association and unless otherwise specified can be filled with one of the following constants: SCTP_FUTURE_ASSOC: Specifies that only future associations created after this socket option will be affected by this call. SCTP_CURRENT_ASSOC: Specifies that only currently existing associations will be affected by this call, and future associations will still receive the previous default value. SCTP_ALL_ASSOC: Specifies that all current and future associations will be affected by this call.
