2023-06-09net: phy: broadcom: Add support for setting LED brightnessFlorian Fainelli
Broadcom PHYs have two LEDs selector registers which allow us to control the LED assignment, including how to turn them on/off. Signed-off-by: Florian Fainelli <florian.fainelli@broadcom.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2023-06-09usbnet: ipheth: add CDC NCM supportFoster Snowhill
Recent iOS releases support CDC NCM encapsulation on RX. This mode is the default on macOS and Windows. In this mode, an iOS device may include one or more Ethernet frames inside a single URB. Freshly booted iOS devices start in legacy mode, but are put into NCM mode by the official Apple driver. When reconnecting such a device from a macOS/Windows machine to a Linux host, the device stays in NCM mode, making it unusable with the legacy ipheth driver code. To correctly support such a device, the driver has to either support the NCM mode too, or put the device back into legacy mode. To match the behaviour of the macOS/Windows driver, and since there is no documented control command to revert to legacy mode, implement NCM support. The device is attempted to be put into NCM mode by default, and falls back to legacy mode if the attempt fails.

2023-06-09usbnet: ipheth: transmit URBs without trailing paddingFoster Snowhill
The behaviour of the official iOS tethering driver on macOS is to not transmit any trailing padding at the end of URBs. This is applicable to both NCM and legacy modes, including older devices. Adapt the driver to not include trailing padding in TX URBs, matching the behaviour of the official macOS driver.

The cleanup precedure in ipheth_probe will attempt to free a NULL pointer in dev->ctrl_buf if the memory allocation for this buffer is not successful. While kfree ignores NULL pointers, and the existing code is safe, it is a better design to rearrange the goto labels and avoid this.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-06-06 1) Support 4 ports VF LAG, part 2/2 2) Few extra trivial cleanup patches Shay Drory Says: ================ Support 4 ports VF LAG, part 2/2 This series continues the series[1] "Support 4 ports VF LAG, part1/2". This series adds support for 4 ports VF LAG (single FDB E-Switch). This series of patches refactoring LAG code that make assumptions about VF LAG supporting only two ports and then enable 4 ports VF LAG. Patch 1: - Fix for ib rep code Patches 2-5: - Refactors LAG layer. Patches 6-7: - Block LAG types which doesn't support 4 ports. Patch 8: - Enable 4 ports VF LAG. This series specifically allows HCAs with 4 ports to create a VF LAG with only 4 ports. It is not possible to create a VF LAG with 2 or 3 ports using HCAs that have 4 ports. Currently, the Merged E-Switch feature only supports HCAs with 2 ports. However, upcoming patches will introduce support for HCAs with 4 ports. In order to activate VF LAG a user can execute: devlink dev eswitch set pci/0000:08:00.0 mode switchdev devlink dev eswitch set pci/0000:08:00.1 mode switchdev devlink dev eswitch set pci/0000:08:00.2 mode switchdev devlink dev eswitch set pci/0000:08:00.3 mode switchdev ip link add name bond0 type bond ip link set dev bond0 type bond mode 802.3ad ip link set dev eth2 master bond0 ip link set dev eth3 master bond0 ip link set dev eth4 master bond0 ip link set dev eth5 master bond0 Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0 pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.

As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

2023-06-08bnxt_en: Query default VLAN before VNIC setup on a VFSomnath Kotur
We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Flip the netif_carrier_ok() condition in queue wake logic. When I moved it to inside __netif_txq_completed_wake() I missed negating it. This made the condition ineffective and could probably lead to crashes.

2023-06-07eth: bnxt: fix the wake conditionJakub Kicinski
The down condition should be the negation of the wake condition, IOW when I moved it from: if (cond && wake()) to if (__netif_txq_completed_wake(cond)) Cond should have been negated. Flip it now. This bug leads to occasional crashes with netconsole. It may also lead to queue never waking up in case BQL is not enabled.

2023-06-07net/mlx5: Skip inline mode check after mlx5_eswitch_enable_locked() failureJiri Pirko
Commit bffaa916588e ("net/mlx5: E-Switch, Add control for inline mode") added inline mode checking to esw_offloads_start() with a warning printed out in case there is a problem. Tne inline mode checking was done even after mlx5_eswitch_enable_locked() call failed, which is pointless. Later on, commit 8c98ee77d911 ("net/mlx5e: E-Switch, Add extack messages to devlink callbacks") converted the error/warning prints to extack setting, which caused that the inline mode check error to overwrite possible previous extack message when mlx5_eswitch_enable_locked() failed. User then gets confusing error message. Fix this by skipping check of inline mode after mlx5_eswitch_enable_locked() call failed.
