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. Matan Azrad (9): net/mlx5: remove Rx queues indexes correlation net/mlx5: add log file procedure for debug data net/mlx5: fix device arguments error detection net/mlx5: mitigate Rx doorbell memory barrier net/mlx5: separate Rx queue initialization net/mlx5: extend Rx completion with error handling net/mlx5: handle Tx completion with error net/mlx5: recover secondary process Rx errors net/mlx5: recover secondary process Tx errors doc/guides/nics/mlx5.rst | 7 + drivers/net/mlx5/mlx5.c | 14 +- drivers/net/mlx5/mlx5.h | 12 + drivers/net/mlx5/mlx5_mp.c | 46 +++ drivers/net/mlx5/mlx5_prm.h | 11 + drivers/net/mlx5/mlx5_rxq.c | 42 +-- drivers/net/mlx5/mlx5_rxtx.c | 673 ++++++++++++++++++++++++++++------ drivers/net/mlx5/mlx5_rxtx.h | 193 +++++----- drivers/net/mlx5/mlx5_rxtx_vec.c | 5 +- drivers/net/mlx5/mlx5_rxtx_vec_neon.h | 36 +- drivers/net/mlx5/mlx5_rxtx_vec_sse.h | 36 +- drivers/net/mlx5/mlx5_trigger.c | 1 + drivers/net/mlx5/mlx5_txq.c | 4 +- 13 files changed, 792 insertions(+), 288 deletions(-)

I'm not really comfortable to take this for 18.11.3. See http://doc.dpdk.org/guides/contributing/stable.html#what-changes-should-be-backported I will take patch 3/9 as it is a fix with Fixes: tag. thanks, Kevin.
