[PATCH v2 net-next 0/3] net: hns3: some cleanups for hns3 driver

From: Jijie Shao

Date: Fri Aug 07 2026 - 05:56:34 EST


Patch 1 sets msg->desc to NULL after kfree to avoid leaving a
dangling pointer in a struct that is reused across loop iterations.

Patch 2 adds the missing const qualifier to the reg parameter of
hclge_log_error(), which is never modified within the function.

Patch 3 uses the txqueue parameter passed by the ndo_tx_timeout
callback directly, instead of iterating all tx queues to find the
timed out one.

---
Changes in v2:
patch3:
- Use h->kinfo.num_tqps for bounds check instead of
ndev->num_tx_queues
- Restore the netif_xmit_timeout_ms() check by making
hns3_dump_timeout_queue() return bool and gating on
its return value, so a cleared stall does not trigger
a reset
- Fold the bounds fix into this patch rather than tracking
it as a separate bugfix, as the OOB has not been
encountered in practice
