Description

In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix TX CQE error handling For an unknown TX CQE error type (probably from a newer hardware), still free the SKB, update the queue tail, etc., otherwise the accounting will be wrong. Also, TX errors can be triggered by injecting corrupted packets, so replace the WARN_ONCE to ratelimited error logging.
