Vasundhara Volam says: ==================== bnxt_en: Updates to devlink info_get cb This series adds support for a generic macro to devlink info_get cb. Adds support for fw.mgmt.api and board.id info to bnxt_en driver info_get cb. Also, updates the devlink-info.rst and bnxt.rst documentation accordingly. This series adds a patch to fix few macro names that maps to bnxt_en firmware versions. v1->v2: Remove ECN dev param, base_mh_addr and serial number info support in this series. Rename drv.spec macro to fw.api. --- v2->v3: Remove hw.addr info as it is per netdev but not per device info. --- v3->v4: Rename "fw.api" to "fw.mgmt.api". Also, add a patch that modifies few macro names in info_get command, to match the devlink documentation. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Ido Schimmel says: ==================== mlxsw: Various static checkers fixes Jakub told me he gets some warnings with W=1, so I decided to check with sparse, smatch and coccinelle as well. This patch set fixes all the issues found. None are actual bugs / regressions and therefore not targeted at net. Patches #1-#2 add missing kernel-doc comments. Patch #3 removes dead code. Patch #4 reworks the ACL code to avoid defining a static variable in a header file. Patch #5 removes unnecessary conversion to bool that coccinelle warns about. Patch #6 avoids false-positive uninitialized symbol errors emitted by smatch. ==================== Signed-off-by: -

The static array 'mlxsw_afk_element_infos' in 'core_acl_flex_keys.h' is copied to each file that includes the header, but not all use it. This results in the following warnings when compiling with W=1: drivers/net/ethernet/mellanox/mlxsw//core_acl_flex_keys.h:76:44: warning: ‘mlxsw_afk_element_infos’ defined but not used [-Wunused-const-variable=] One way to suppress the warning is to mark the array with '__maybe_unused', but another option is to remove it from the header file entirely. Change 'struct mlxsw_afk_element_inst' to store the key to the array ('element') instead of the array value keyed by 'element'. Adjust the different users accordingly. Signed-off-by: -

So far we set phydev->suspended to true in phy_suspend() even if the PHY driver doesn't implement the suspend callback. This applies accordingly for the resume path. The current behavior doesn't cause any issue I'd be aware of, but it's not logical and misleading, especially considering the description of the flag: "suspended: Set to true if this phy has been suspended successfully" Signed-off-by:

Igor Russkikh says: ==================== net: atlantic: MACSec support for AQC devices This patchset introduces MACSec HW offloading support in Marvell(Aquantia) AQC atlantic driver. This implementation is a joint effort of Marvell developers on top of the work started by Antoine Tenart. v2: * clean up the generated code (removed useless bit operations); * use WARN_ONCE to avoid log spam; * use put_unaligned_be64; * removed trailing \0 and length limit for format strings; v1: https://patchwork.ozlabs.org/cover/1259998/ RFC v2: https://patchwork.ozlabs.org/cover/1252204/ RFC v1: https://patchwork.ozlabs.org/cover/1238082/ Several patches introduce backward-incompatible changes and are subject for discussion/drop: 1) patch 0007: multicast/broadcast when offloading is needed to handle ARP requests, because they have broadcast destination address; With this patch we also match and encrypt/decrypt packets between macsec hw and realdev based on device's mac address. This can potentially be used to support multiple macsec offloaded interfaces on top of one realdev. However in some environments this could lead to problems, e.g. the 'bridge over macsec' configuration will expect the packets with unknown src MAC should come through macsec. The patch is questionable, we've used it because our current hw setup and requirements both assume that the decryption is done based on mac address match only. This could be changed by encrypting/decripting all the traffic (except control). 2) patch 0009: real_dev features are now propagated to macsec device (when HW offloading is enabled), otherwise feature set might lead to HW reconfiguration during MACSec configuration. Also, HW offloaded macsec should be able to keep LRO LSO features, since they are transparent for macsec engine (at least in our hardware). ==================== Signed-off-by:

This patch makes real_dev_feature propagation by MACSec offloaded device. Issue description: real_dev features are disabled upon macsec creation. Root cause: Features limitation (specific to SW MACSec limitation) is being applied to HW offloaded case as well. This causes 'set_features' request on the real_dev with reduced feature set due to chain propagation. Proposed solution: Report real_dev features when HW offloading is enabled. NB! MACSec offloaded device does not propagate VLAN offload features at the moment. This can potentially be added later on as a separate patch. Note: this patch requires HW offloading to be enabled by default in order to function properly. Signed-off-by:

This is trivial since we already have support for the entirely identical (from the kernel's point of view) RDNSS, DNSSL, etc. that also contain opaque data that needs to be passed down to userspace for further processing. As specified in draft-ietf-6man-ra-pref64-09 (while it is still a draft, it is purely waiting on the RFC Editor for cleanups and publishing): PREF64 option contains lifetime and a (up to) 96-bit IPv6 prefix. The 8-bit identifier of the option type as assigned by the IANA is 38. Since we lack DNS64/NAT64/CLAT support in kernel at the moment, thus this option should also be passed on to userland.

Grygorii Strashko says: ==================== net: ethernet: ti: add networking support for k3 am65x/j721e soc This v6 series adds basic networking support support TI K3 AM654x/J721E SoC which have integrated Gigabit Ethernet MAC (Media Access Controller) into device MCU domain and named MCU_CPSW0 (CPSW2G NUSS). Formally TRMs refer CPSW2G NUSS as two-port Gigabit Ethernet Switch subsystem with port 0 being the CPPI DMA host port and port 1 being the external Ethernet port, but for 1 external port device it's just Port 0 <-> ALE <-> Port 1 and it's rather device with HW filtering capabilities then actually switching device. It's expected to have similar devices, but with more external ports. The new Host port 0 Communications Port Programming Interface (CPPI5) is operating by TI AM654x/J721E NAVSS Unified DMA Peripheral Root Complex (UDMA-P) controller [1]. The CPSW2G contains below modules for which existing code is re-used: - MAC SL: cpsw_sl.c - Address Lookup Engine (ALE): cpsw_ale.c, basically compatible with K2 66AK2E/G - Management Data Input/Output interface (MDIO): davinci_mdio.c, fully compatible with TI AM3/4/5 devices Basic features supported by CPSW2G NUSS driver: - VLAN support, 802.1Q compliant, Auto add port VLAN for untagged frames on ingress, Auto VLAN removal on egress and auto pad to minimum frame size. - multicast filtering - promisc mode - TX multiq support in Round Robin or Fixed priority modes - RX checksum offload for non-fragmented IPv4/IPv6 TCP/UDP packets - TX checksum offload support for IPv4/IPv6 TCP/UDP packets (J721E only). Features under development: - Support for IEEE 1588 Clock Synchronization. The CPSW2G NUSS includes new version of Common Platform Time Sync (CPTS) - tc-mqprio: priority level Quality Of Service (QOS) support (802.1p) - tc-cbs: Support for Audio/Video Bridging (P802.1Qav/D6.0) HW shapers - tc-taprio: IEEE 802.1Qbv/D2.2 Enhancements for Scheduled Traffic - frame preemption: IEEE P902.3br/D2.0 Interspersing Express Traffic, 802.1Qbu - extended ALE features: classifier/policers, auto-aging Patches 1-6 are intended for netdev, Patches 7-11 are intended for K3 Platform tree and provided here for testing purposes. Changes in v6: - fixed comments from Rob Herring <robh@kernel.org> and added his Reviewed-by. - added Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Changes in v5: - renamed files k3-udma-desc-pool.* k3-udma-desc-pool to k3-cppi-desc-pool.*, and API to k3_cppi_desc_pool_* as requested by Peter Ujfalusi <peter.ujfalusi@ti.com> - fixed copy-paste err in am65_cpsw_nuss_ndo_slave_set_rx_mode() which blocked recieving of mcast frames. - added Tested-by: Murali Karicheri <m-karicheri2@ti.com> Changes in v4: - fixed minor comments from Jakub Kicinski <kuba@kernel.org> - dependencies resolved: required phy-rmii-sel changes [2] queued for merge except one [3] which is included in this series with Kishon's ask.
