Marek Behún says: ==================== net: phy: marvell10g updates Here are some updates for marvell10g PHY driver. I am still working on some more changes for this driver, but I would like to have at least something reviewed / applied. Changes since v3: - added Andrew's Reviewed-by tags - removed patches adding variadic-macro library and bitmap initialization macro - it causes warning that we are not currently able to fix easily. Instead the supported_interfaces bitmap is now initialized via a chip specific method - added explanation of mactype initialization to commit message of patch 07/16 - fixed repeated word in commit message of second to last patch Changes since v2: - code refactored to use an additional structure mv3310_chip describing mv3310 specific properties / operations for PHYs supported by this driver - added separate phy_driver structures for 88X3340 and 88E2111 - removed 88E2180 specific code (dual-port and quad-port SXGMII modes are ignored for now) Changes since v1: - added various MACTYPEs support also for 88E21XX - differentiate between specific models with same PHY_ID - better check for compatible interface - print exact model ==================== Signed-off-by: -

The 88X3340 contains 4 cores similar to 88X3310, but there is a difference: it does not support xaui host mode. Instead the corresponding MACTYPE means rxaui / 5gbase-r / 2500base-x / sgmii without AN Signed-off-by:

Add support for all rate matching modes for 88X3310 (currently only 10gbase-r is supported, but xaui and rxaui can also be used). Add support for rate matching for 88E2110 (on 88E2110 the MACTYPE register is at a different place). Currently rate matching mode is selected by strapping pins (by setting the MACTYPE register). There is work in progress to enable this driver to deduce the best MACTYPE from the knowledge of which interface modes are supported by the host, but this work is not finished yet. Signed-off-by:

The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port (a u16) left 24 places. There are two subtle issues here, first the shift gets promoted to an signed int and then sign extended to a u64. If oct->pcie_port is 0x80 or more then the upper bits get sign extended to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it needs to be cast to a u64 for all the bits to not overflow. It is entirely possible that the u16 port value is never large enough for this to fail, but it is useful to fix unintended overflows such as this. Fix this by casting the port parameter to the macro to a u64 before the shift.

Merge tag 'linux-can-next-for-5.13-20210407' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2021-04-07 this is a pull request of 6 patches for net-next/master. The first patch targets the CAN driver infrastructure, it improves the alloc_can{,fd}_skb() function to set the pointer to the CAN frame to NULL if skb allocation fails. The next patch adds missing error handling to the m_can driver's RX path (the code was introduced in -next, no need to backport). In the next patch an unused constant is removed from an enum in the c_can driver. The last 3 patches target the mcp251xfd driver. They add BQL support and try to work around a sometimes broken CRC when reading the TBC register. ==================== Signed-off-by:

Here is only one place where we want to specify new_ifindex. In all other cases, callers pass 0 as new_ifindex. It looks reasonable to add a low-level function with new_ifindex and to convert dev_change_net_namespace to a static inline wrapper.

Saeed Mahameed says: ==================== mlx5-updates-2021-04-06 Introduce TC sample offload Background ---------- The tc sample action allows user to sample traffic matched by tc classifier. The sampling consists of choosing packets randomly and sampling them using psample module. The tc sample parameters include group id, sampling rate and packet's truncation (to save kernel-user traffic). Sample in TC SW --------------- User must specify rate and group id for sample action, truncate is optional. tc filter add dev enp4s0f0_0 ingress protocol ip prio 1 flower \ src_mac 02:25:d0:14:01:02 dst_mac 02:25:d0:14:01:03 \ action sample rate 10 group 5 trunc 60 \ action mirred egress redirect dev enp4s0f0_1 The tc sample action kernel module 'act_sample' will call another kernel module 'psample' to send sampled packets to userspace. MLX5 sample HW offload - MLX5 driver patches -------------------------------------------- The sample action is translated to a goto flow table object destination which samples packets according to the provided sample ratio. Sampled packets are duplicated. One copy is processed by a termination table, named the sample table, which sends the packet to the eswitch manager port (that will be processed by software). The second copy is processed by the default table which executes the subsequent actions. The default table is created per <vport, chain, prio> tuple as rules with different prios and chains may overlap. For example, for the following typical flow table: +-------------------------------+ + original flow table + +-------------------------------+ + original match + +-------------------------------+ + sample action + other actions + +-------------------------------+ We translate the tc filter with sample action to the following HW model: +---------------------+ + original flow table + +---------------------+ + original match + +---------------------+ | v +------------------------------------------------+ + Flow Sampler Object + +------------------------------------------------+ + sample ratio + +------------------------------------------------+ + sample table id | default table id + +------------------------------------------------+ | | v v +-----------------------------+ +----------------------------------------+ + sample table + + default table per <vport, chain, prio> + +-----------------------------+ +----------------------------------------+ + forward to management vport + + original match + +-----------------------------+ +----------------------------------------+ + other actions + +----------------------------------------+ Flow sampler object ------------------- Hardware introduces flow sampler object to do sample. It is a new destination type. Driver needs to specify two flow table ids in it. One is sample table id. The other one is the default table id. Sample table samples the packets according to the sample rate and forward the sampled packets to eswitch manager port. Default table finishes the subsequent actions. Group id and reg_c0 ------------------- Userspace program will take different actions for sampled packets according to tc sample action group id. So hardware must pass group id to software for each sampled packets. In Paul Blakey's "Introduce connection tracking offload" patch set, reg_c0 lower 16 bits are used for miss packet chain id restore. We convert reg_c0 lower 16 bits to a common object pool, so other features can also use it. Since sample group id is 32 bits, create a 16 bits object id to map the group id and write the object id to reg_c0 lower 16 bits. reg_c0 can only be used for matching. Write reg_c0 to flow_tag, so software can get the object id via flow_tag and find group id via the common object pool. Sampler restore handle ---------------------- Use common object pool to create an object id to map sample parameters. Allocate a modify header action to write the object id to reg_c0 lower 16 bits. Create a restore rule to pass the object id to software. So software can identify sampled packets via the object id and send it to userspace. Aggregate the modify header action, restore rule and object id to a sample restore handle. Re-use identical sample restore handle for the same object id. Send sampled packets to userspace --------------------------------- The destination for sampled packets is eswitch manager port, so representors can receive sampled packets together with the group id. Driver will send sampled packets and group id to userspace via psample. ==================== Signed-off-by: -

In function fdp_nci_patch_otp and fdp_nci_patch_ram，many goto out statements are used, and out label just return variable r. in some places,just jump to the out label, and in other places, assign a value to the variable r,then jump to the out label. It is unnecessary, we just use return sentences to replace goto sentences and delete out label. Signed-off-by:

Disable software thermal protection by removing critical trip points from all thermal zones. The software thermal protection is redundant given there are two layers of protection below it in firmware and hardware. The first layer is performed by firmware, the second, in case firmware was not able to perform protection, by hardware. The temperature threshold set for hardware protection is always higher than for firmware. Signed-off-by:
