Add Switch LED for each port for MikroTik RB3011UiAS-RM. MikroTik RB3011UiAS-RM is a 10 port device with 2 qca8337 switch chips connected. It was discovered that in the hardware design all 3 Switch LED trace of the related port is connected to the same LED. This was discovered by setting to 'always on' the related led in the switch regs and noticing that all 3 LED for the specific port (for example for port 1) cause the connected LED for port 1 to turn on. As an extra test we tried enabling 2 different LED for the port resulting in the LED turned off only if every led in the reg was off. Aside from this funny and strange hardware implementation, the device itself have one green LED for each port, resulting in 10 green LED one for each of the 10 supported port.

IPQ8064 MikroTik RB3011UiAS-RM DT have currently unevaluted properties in the 2 switch nodes. The bindings #address-cells and #size-cells are redundant and cause warning for 'Unevaluated properties are not allowed'. Drop these bindings to mute these warning as they should not be there from the start. Cc: Jonathan McDowell <noodles@earth.li> Signed-off-by:

Document support for LEDs node in ethernet-controller. Ethernet Controller may support different LEDs that can be configured for different operation like blinking on traffic event or port link. Also add some Documentation to describe the difference of these nodes compared to PHY LEDs, since ethernet-controller LEDs are controllable by the ethernet controller regs and the possible intergated PHY doesn't have control on them.

Andrew Lunn authored
Linux LEDs can be software controlled via the brightness file in /sys. LED drivers need to implement a brightness_set function which the core will call. Implement an intermediary in phy_device, which will call into the phy driver if it implements the necessary function. Signed-off-by:

Define common binding parsing for all PHY drivers with LEDs using phylib. Parse the DT as part of the phy_probe and add LEDs to the linux LED class infrastructure. For the moment, provide a dummy brightness function, which will later be replaced with a call into the PHY driver. This allows testing since the LED core might otherwise reject an LED whose brightness cannot be set. Add a dependency on LED_CLASS. It either needs to be built in, or not enabled, since a modular build can result in linker errors. Signed-off-by:

Andrew Lunn authored
Provide stubs for devm_led_classdev_register_ext() and led_init_default_state_get() so that LED drivers embedded within other drivers such as PHYs and Ethernet switches still build when LEDS_CLASS or NEW_LEDS are disabled. This also helps with Kconfig dependencies, which are somewhat hairy for phylib and mdio and only get worse when adding a dependency on LED_CLASS. Signed-off-by:

Add LEDs basic support for qca8k Switch Family by adding basic brightness_set() support. Since these LEDs refelect port status, the default label is set to ":port". DT binding should describe the color and function of the LEDs using standard LEDs api. Each LED always have the device name as prefix. The device name is composed from the mii bus id and the PHY addr resulting in example names like: - qca8k-0.0:00:amber:lan - qca8k-0.0:00:white:lan - qca8k-0.0:01:amber:lan - qca8k-0.0:01:white:lan These LEDs supports only blocking variant of the brightness_set() function since they can sleep during access of the switch leds to set the brightness. While at it add to the qca8k header file each mode defined by the Switch Documentation for future use. Signed-off-by:

Tariq Toukan says: ==================== net/mlx5e: Extend XDP multi-buffer capabilities This series extends the XDP multi-buffer support in the mlx5e driver. Patchset breakdown: - Infrastructural changes and preparations. - Add XDP multi-buffer support for XDP redirect-in. - Use TX MPWQE (multi-packet WQE) HW feature for non-linear single-segmented XDP frames. - Add XDP multi-buffer support for striding RQ. In Striding RQ, we overcome the lack of headroom and tailroom between the RQ strides by allocating a side page per packet and using it for the xdp_buff descriptor. We structure the xdp_buff so that it contains nothing in the linear part, and the whole packet resides in the fragments.

Here we add support for multi-buffer XDP handling in Striding RQ, which is our default out-of-the-box RQ type. Before this series, loading such an XDP program would fail, until you switch to the legacy RQ (by unsetting the rx_striding_rq priv-flag). To overcome the lack of headroom and tailroom between the strides, we allocate a side page to be used for the descriptor (xdp_buff / skb) and the linear part. When an XDP program is attached, we structure the xdp_buff so that it contains no data in the linear part, and the whole packet resides in the fragments. In case of XDP_PASS, where an SKB still needs to be created, we copy up to 256 bytes to its linear part, to match the current behavior, and satisfy functions that assume finding the packet headers in the SKB linear part (like eth_type_trans). Performance testing: Packet rate test, 64 bytes, 32 channels, MTU 9000 bytes. CPU: Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz.

Under a few restrictions, TX MPWQE feature can serve multiple TX packets in a single TX descriptor. It requires each of the packets to have a single scatter entry / segment. Today we allow only linear frames to use this feature, although there's no real problem with non-linear ones where the whole packet reside in the first fragment. Expand the XDP TX MPWQE feature support to include such frames. This is in preparation for the downstream patch, in which we will generate such non-linear frames. Signed-off-by:

Function mlx5e_rx_get_linear_stride_sz() returns PAGE_SIZE immediately in case an XDP program is attached. The more accurate formula is ALIGN(sz, PAGE_SIZE), to prevent two packets from residing on the same page. The assumption behind the current code is that sz <= PAGE_SIZE holds for all cases with XDP program set. This is true because it is being called from: - 3 times from Striding RQ flows, in which XDP is not supported for such large packets. - 1 time from Legacy RQ flow, under the condition mlx5e_rx_is_linear_skb(). No functional change here, just removing the implied assumption in preparation for supporting XDP multi-buffer in Striding RQ. Reviewed-by:

Handle multi-buffer XDP redirect-in requests coming through mlx5e_xdp_xmit.

Here we fix the current wi->num_pkts abuse, as it was used to indicate multiple xdpi entries in the xdpi_fifo. Instead, reduce mlx5e_xdp_info to the size of a single field, making it a union of unions. Per packet, use as many instances as needed to provide the information needed at the time of completion. The sequence of xdpi instances pushed is well defined, derived by the xmit_mode. Reviewed-by:

Introduce struct mlx5e_xmit_data_frags to be used for non-linear xmit buffers. Let it include sinfo pointer. Take one bit from the len field to indicate if the descriptor has fragments and can be casted-up into the extended version. Zero-init to make sure has_frags, and potentially future fields, are zero when not explicitly assigned. Another field will be added in a downstream patch to indicate and point to dma addresses of the different frags, for redirect-in requests.

Currently, bonding only obtain the timestamp (ts) information of the active slave, which is available only for modes 1, 5, and 6. For other modes, bonding only has software rx timestamping support. However, some users who use modes such as LACP also want tx timestamp support. To address this issue, let's check the ts information of each slave. If all slaves support tx timestamping, we can enable tx timestamping support for the bond. Add a note that the get_ts_info may be called with RCU, or rtnl or reference on the device in ethtool.h> Suggested-by:
