linux.git/net/core/netdev_work.c, branch v7.2-rc1 Linux kernel source tree net: add the driver-facing netdev_work scheduling API 2026-06-25T17:18:40+00:00 Jakub Kicinski kuba@kernel.org 2026-06-24T18:20:16+00:00 129cdce9da9e44c52d38889e0411be9817bca114 With an extra event mask we can easily extend the netdev work to also service driver-defined events. For advanced drivers this is probably not a perfect match, but it makes running deferred work easier in simple cases. Expose the netdev_work facility to drivers. Add helpers to schedule work and a dedicated ndo to perform the driver- -scheduled actions.

net: turn the rx_mode work into a generic netdev_work facility 2026-06-25T17:18:40+00:00 Jakub Kicinski kuba@kernel.org 2026-06-24T18:20:15+00:00 12c765be84d28f22deca10e775889f54bd571a85 The rx_mode update runs from a workqueue: drivers have their ndo_set_rx_mode_async() callback executed by a single global work item under RTNL and ops lock. This is a useful pattern. Support multiple "events" that need to be serviced and make RX_MODE sync the first one. Call the events "core" because later on we will let drivers define and schedule their own.
