From: Sebastian Roland Wolf <redacted> Add a null pointer check to prevent kernel crashes when hardware offloading is active on MediaTek devices. In some edge cases, the ethernet pointer or its associated netdev element can be NULL. Checking these pointers before access is mandatory to avoid segmentation faults and kernel oops.
Would it make sense to return EOPNOTSUPP, or maybe ENODEV? This does
seem like an error case.
