2025-03-08net/mlx5: Limit non-privileged commandsChiara Meiohas
Limit non-privileged UID commands to half of the available command slots when privileged UIDs are present. Privileged throttle commands will not be limited. Use an xarray to store privileged UIDs. Add insert and remove functions for privileged UIDs management. Non-user commands (with uid 0) are not limited.

2025-03-08net/mlx5: Allow the throttle mechanism to be more dynamicChiara Meiohas
Previously, throttle commands were identified and limited based on opcode. These commands were limited to half the command slots using a semaphore, and callback commands checked the opcode to determine semaphore release. To allow exceptions, we introduce a variable to indicate when the throttle lock is held. This allows scenarios where throttle commands are not limited. Callback functions use this variable to determine if the throttle semaphore needs to be released. This patch contains no functional changes. It's a preparation for the next patch.

2025-03-08net: move misc netdev_lock flavors to a separate headerJakub Kicinski
Move the more esoteric helpers for netdev instance lock to a dedicated header. This avoids growing netdevice.h to infinity and makes rebuilding the kernel much faster (after touching the header with the helpers). The main netdev_lock() / netdev_unlock() functions are used in static inlines in netdevice.h and will probably be used most commonly, so keep them in netdevice.h.

2025-03-06net: stmmac: simplify phylink_suspend() and phylink_resume() callsRussell King (Oracle)
Currently, the calls to phylink's suspend and resume functions are inside overly complex tests, and boil down to: if (device_may_wakeup(priv->device) && priv->plat->pmt) { call phylink } else { call phylink and if (device_may_wakeup(priv->device)) do something else } This results in phylink always being called, possibly with differing arguments for phylink_suspend(). Simplify this code, noting that each site is slightly different due to the order in which phylink is called and the "something else".

2025-03-06net: stmmac: mostly remove "buf_sz"Russell King (Oracle)
The "buf_sz" parameter is not used in the stmmac driver - there is one place where the value of buf_sz is validated, and two places where it is written. It is otherwise unused. Remove these accesses. However, leave the module parameter in place as removing it could cause module load to fail, breaking user setups.

2025-03-06eth: bnxt: remove most dependencies on RTNLStanislav Fomichev
Only devlink and sriov paths are grabbing rtnl explicitly. The rest is covered by netdev instance lock which the core now grabs, so there is no need to manage rtnl in most places anymore. On the core side we can now try to drop rtnl in some places (do_setlink for example) for the drivers that signal non-rtnl mode (TBD). Boot-tested and with `ethtool -L eth1 combined 24` to trigger reset.

For the drivers that use queue management API, switch to the mode where core stack holds the netdev instance lock. This affects the following drivers: - bnxt - gve - netdevsim Originally I locked only start/stop, but switched to holding the lock over all iterations to make them look atomic to the device (feels like it should be easier to reason about).
