Add support for data-path Rx and Tx completions with error handling: 1. Detect the error. 2. Do not crash. 3. Report it in statistics counters. 4. Dump debug information to system log file. 5. Recover the error under the hood. 6. Add support for secondary process recovery.
No performance impact was shown.
