[PATCH net v5 0/2] net: cpsw: Execute ndo_set_rx_mode callback in a work queue

[Kevin Hao <haokexin@gmail.com>]

These two patches resolve an RTNL assertion call trace issue in both the legacy
and new cpsw drivers.

Thanks,
Kevin

Changes in v5:
- Apply the same fix to the legacy cpsw driver as well.

- Use goto label in cpsw_ndo_set_rx_mode_work() for the undo path as
  suggested by Jakub.

- Move the disable_work_sync() call to after unregister_netdev() as
  suggested by Jakub.

- Link to v4: https://lore.kernel.org/r/20260130-bbb-v4-1-2bd000a15c34@gmail.com

Changes in v4:
- Using schedule_work() instead of creating a dedicated workqueue.

- Link to v3: https://lore.kernel.org/r/20260127-bbb-v3-1-5e71f340c1e9@gmail.com

Changes in v3:
- Resolve the deadlock issue identified in the AI review [2]
  by moving the netif_running() check under the RTNL lock and removing the
  cancel_work_sync() call in cpsw_ndo_stop().

- Link to v2: https://lore.kernel.org/r/20260125-bbb-v2-1-1547ffabc9d3@gmail.com

Changes in v2:
- Addresses the issue identified in the AI review [1]:
  - Adds a netif_running() check in cpsw_ndo_set_rx_mode_work()
  - Cancels the rx_mode_work in cpsw_ndo_stop()

- Link to v1: https://lore.kernel.org/r/20260123-bbb-v1-1-176b0b71834d@gmail.com
