2021-10-14ethernet: constify references to netdev->dev_addr in driversJakub Kicinski
This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

2021-10-14ice: Implement support for SMA and U.FL on E810-TMaciej Machnikowski
Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and allow controlling them. E810-T adapters are equipped with: - 2 external bidirectional SMA connectors - 1 internal TX U.FL - 1 internal RX U.FL U.FL connectors share signal lines with the SMA connectors. The TX U.FL1 share the line with the SMA1 and the RX U.FL2 share line with the SMA2. This dependence is controlled by the ice_verify_pin_e810t. Additionally add support for the E810-T-based devices which don't use the SMA/U.FL controller. If the IO expander is not detected don't expose pins and use 2 predefined 1PPS input and output pins.

2021-10-14ice: Add support for SMA control multiplexerMaciej Machnikowski
E810-T adapters have two external bidirectional SMA connectors and two internal unidirectional U.FL connectors. Multiplexing between U.FL and SMA and SMA direction is controlled using the PCA9575 expander.

2021-10-13mlxsw: spectrum_qdisc: Introduce per-TC ECN countersPetr Machata
The Qdisc code in mlxsw used to report a number of packets ECN-marked on a port. Because reporting a per-port value as a per-TC value was misleading, this was removed in commit 8a29581eb001 ("mlxsw: spectrum: Move the ECN-marked packet counter to ethtool"). On Spectrum-3, a per-TC number of ECN-marked packets is available in per-TC congestion counter group. Add a new array for the ECN counter, fetch the values from the per-TC congestion group, and pick the value indicated by tclass_num as appropriate. On Spectrum-1 and Spectrum-2, this per-TC value is not available, and zeroes will be reported, as they currently are.

Commit a0c76345e3d3 ("devlink: disallow reload operation during device cleanup") added devlink_reload_{enable,disable}() APIs to prevent reload operation from racing with device probe/dismantle. After recent changes to move devlink_register() to the end of device probe and devlink_unregister() to the beginning of device dismantle, these races can no longer happen. Reload operations will be denied if the devlink instance is unregistered and devlink_unregister() will block until all in-flight operations are done.

2021-10-12net: hns: Prefer struct_size over open coded arithmeticLen Baker
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, take the opportunity to refactor the hnae_handle structure to switch the last member to flexible array, changing the code accordingly. Also, fix the comment in the hnae_vf_cb structure to inform that the ae_handle member must be the last member. Then, use the struct_size() helper to do the arithmetic instead of the argument "size + count * size" in the kzalloc() function. This code was detected with the help of Coccinelle and audited and fixed manually.

Therefore keep track of which actions are permissible at each binding block. When an attempt is made to bind a certain action at a binding point where it is not supported, bounce the request.
