ena: Add differentiation for missing TX completions reset 2024-10-31T14:54:11+00:00 Osama Abboud osamaabb@amazon.com 2024-08-07T06:24:19+00:00 db0c751ed7f1dc1c2c3daeaafa9c5354f48b8589 This commit adds differentiation for a reset caused by missing tx completions, by verifying if the driver didn't receive tx completions caused by missing interrupts. The cleanup_running field was added to ena_ring because cleanup_task.ta_pending is zeroed before ena_cleanup() runs. Also ena_increment_reset_counter() API was added in order to support only incrementing the reset counter. Approved by: cperciva (mentor) Sponsored by: Amazon, Inc.
