2025-03-06net/mlx5e: Properly match IPsec subnet addressesLeon Romanovsky
Existing match criteria didn't allow to match whole subnet and only by specific addresses only. This caused to tunnel mode do not forward such traffic through relevant SA. In tunnel mode, policies look like this: src 192.169.0.0/16 dst 192.169.0.0/16 dir out priority 383615 ptype main tmpl src 192.169.101.2 dst 192.169.101.1 proto esp spi 0xc5141c18 reqid 1 mode tunnel crypto offload parameters: dev eth2 mode packet In this case, the XFRM core code handled all subnet calculations and forwarded network address to the drivers e.g. 192.169.0.0. For mlx5 devices, there is a need to set relevant prefix e.g. 0xFFFF00 to perform flow steering match operation.

2025-03-06net/mlx5e: Enable lanes configuration when auto-negotiation is offShahar Shitrit
Currently, when auto-negotiation is disabled, the driver retrieves the speed and converts it into all link modes that correspond to that speed. With this patch, we add the ability to set the number of lanes, so that the combination of speed and lanes corresponds to exactly one specific link mode for the extended bit map. For the legacy bit map the driver sets all link modes correspond to speed and lanes. This change provides users with the option to set a specific link mode, rather than enabling all link modes associated with a given speed when auto-negotiation is off.

Introduce struct mlx5_link_info with a speed field and change the types of mlx5e_link_speed and mlx5e_ext_link_speed from arrays of u32 to arrays of struct mlx5_link_info. These arrays are renamed to mlx5e_link_info and mlx5e_ext_link_info, respectively. This change prepares for a future patch that will introduce a lanes field in struct mlx5_link_info and add lanes mapping alongside the speed for each link mode in the two arrays.

icss_iep_perout_enable_hw() is a common function for generating both pps and perout signals. When enabling pps, the application needs to only pass enable/disable argument, whereas for perout it supports different flags to configure the signal. In case the app passes a valid phase offset value, the signal should start toggling after that phase offset, else start immediately or as soon as possible. ICSS_IEP_SYNC_START_REG register take number of clock cycles to wait before starting the signal after activation time. Set appropriate value to this register to support phase offset.

2025-03-06net: tun: Enable transfer of XDP metadata to skbMarcus Wichelmann
When the XDP metadata area was used, it is expected that the same metadata can also be accessed from TC, as can be read in the description of the bpf_xdp_adjust_meta helper function. In the tun driver, this was not yet implemented. To make this work, the skb that is being built on XDP_PASS should know of the current size of the metadata area. This is ensured by adding calls to skb_metadata_set. For the tun_xdp_one code path, an additional check is necessary to handle the case where the externally initialized xdp_buff has no metadata support (xdp->data_meta == xdp->data + 1). More information about this feature can be found in the commit message of commit de8f3a83b0a0 ("bpf: add meta pointer for direct access").

2025-03-06net: tun: Enable XDP metadata supportMarcus Wichelmann
Enable the support for the bpf_xdp_adjust_meta helper function for XDP buffers initialized by the tun driver. This allows to reserve a metadata area that is useful to pass any information from one XDP program to another one, for example when using tail-calls. Whether this helper function can be used in an XDP program depends on how the xdp_buff was initialized. Most net drivers initialize the xdp_buff in a way, that allows bpf_xdp_adjust_meta to be used. In case of the tun driver, this is currently not the case. There are two code paths in the tun driver that lead to a bpf_prog_run_xdp and where metadata support should be enabled: 1. tun_build_skb, which is called by tun_get_user and is used when writing packets from userspace into the device. In this case, the xdp_buff created in tun_build_skb has no support for bpf_xdp_adjust_meta and calls of that helper function result in ENOTSUPP. For this code path, it's sufficient to set the meta_valid argument of the xdp_prepare_buff call. The reserved headroom is large enough already. 2. tun_xdp_one, which is called by tun_sendmsg which again is called by other drivers (e.g. vhost_net). When the TUN_MSG_PTR mode is used, another driver may pass a batch of xdp_buffs to the tun driver. In this case, that other driver is the one initializing the xdp_buff. See commit 043d222f93ab ("tuntap: accept an array of XDP buffs through sendmsg()") for details. For now, the vhost_net driver is the only one using TUN_MSG_PTR and it already initializes the xdp_buffs with metadata support and sufficient headroom. But the tun driver disables it again, so the xdp_set_data_meta_invalid call has to be removed.

2025-03-06mctp i3c: handle NULL header addressMatt Johnston
daddr can be NULL if there is no neighbour table entry present, in that case the tx packet should be dropped. saddr will usually be set by MCTP core, but check for NULL in case a packet is transmitted by a different protocol.

2025-03-05net: dsa: mt7530: Fix traffic flooding for MMIO devicesLorenzo Bianconi
On MMIO devices (e.g. MT7988 or EN7581) unicast traffic received on lanX port is flooded on all other user ports if the DSA switch is configured without VLAN support since PORT_MATRIX in PCR regs contains all user ports. Similar to MDIO devices (e.g. MT7530 and MT7531) fix the issue defining default VLAN-ID 0 for MT7530 MMIO devices.

2025-03-05net: stmmac: configure SerDes according to the interface modeChoong Yong Liang
Intel platform will configure the SerDes through PMC API based on the provided interface mode. This patch adds several new functions below:- - intel_tsn_lane_is_available(): This new function reads FIA lane ownership registers and common lane registers through IPC commands to know which lane the mGbE port is assigned to. - intel_mac_finish(): To configure the SerDes based on the assigned lane and latest interface mode, it sends IPC command to the PMC through PMC driver/API. The PMC acts as a proxy for R/W on behalf of the driver. - intel_set_reg_access(): Set the register access to the available TSN interface.

The xpcs_switch_interface_mode function was introduced to handle interface switching. According to the XPCS datasheet, a soft reset is required to initiate Clause 37 auto-negotiation when the XPCS switches interface modes. When the interface mode switches from 2500BASE-X to SGMII, re-initiating Clause 37 auto-negotiation is required for the SGMII interface mode to function properly.
