[PATCH net-next v3 0/5] net: wangxun: timeout and error

[Jiawen Wu <jiawenwu@trustnetic.com>]

This series is a split of the previous series:
https://lore.kernel.org/all/20260326021406.30444-1-jiawenwu@trustnetic.com

It is about adding the Tx timeout process and pci_error_handlers.

Changes log:
v3:
- Merge the multiple string line into one in wx_handle_tx_hang().
- Remove the redundant warn messages.
- Use test_and_clear_bit() instead of checking the flag bit then clear it.
- Drop the Tx hang check in tx_timeout.
- Call wx_update_stats() before wx_check_tx_hang().
- Add Tx flush when link lost.
- Move wx_ptp_stop() into wx->close_suspend().
- Drop V2 patch 5/6 because WOL packets are handled before DMA ring.
- Check wx NULL pointer in wx_io_error_detected().
- Check perm failure before hardware teardown.

v2: https://lore.kernel.org/all/20260430082517.19612-1-jiawenwu@trustnetic.com
- Add the missing rtnl_unlock() at early return in wx_reset_subtask().
- Replace ngbe_close() with ngbe_close_suspend() in ngbe_dev_shutdown().
- Add a patch to clear stored DMA addresses.
 
v1: https://lore.kernel.org/r/20260428021156.13564-1-jiawenwu@trustnetic.com

The changes from the last full patch set V6:
- Add 'else' handling in ngbe_do_reset().
- Acquire rtnl_lock() before checking netif_running() in
  wx_reset_subtask().
- Use test_and_clear_bit() instead of test_bit()…clear_bit() to avoid
  losing another reset request.
- Change ‘u64 tx_done_old’ to ‘u32’ to avoid data race between
  dev_watchdog and NAPI polling.
- Check the return value of ndo_open() in wx_io_resume().
- Drop pci_save_state().
