2018-03-27net/mlx5e: Recover Send Queue (SQ) from error stateEran Ben Elisha
An error TX completion (CQE) which arrived on a specific SQ indicates that this SQ got moved by the hardware to error state, which means all pending and incoming TX requests are dropped or will be dropped and no further "Good" CQEs will be generated for that SQ. Before this patch TX completions (CQEs) were not monitored and were handled as a regular CQE. This caused the SQ to stay in an error state, making it useless for xmiting new packets. Mitigation plan: In case of an error completion, schedule a recovery work which would do the following: - Mark the TXQ as DRV_XOFF to disable new packets to arrive from the stack - NAPI to flush all pending SQ WQEs (via flush_in_error_en bit) to release SW and HW resources(SKB, DMA, etc) and have the SQ and CQ consumer/producer indices synced. - Modify the SQ state ERR -> RST -> RDY (restart the SQ). - Reactivate the SQ and reset SQ cc and pc If we identify two consecutive requests for SQ recover in less than 500 msecs, drop the recover request to avoid CPU overload, as this scenario most likely happened due to a severe repeated bug. In addition, add SQ recover SW counter to monitor successful recoveries. Signed-off-by: Eran Ben Elisha <eranbe@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2018-03-27net/mlx5e: Move all TX timeout logic to be under state lockEran Ben Elisha
Driver callback for handling TX timeout should access some internal resources (SQ, CQ) in order to decide if the tx timeout work should be scheduled. These resources might be unavailable if channels are closed in parallel (ifdown for example). The state lock is the mechanism to protect from such races. Move all TX timeout logic to be in the work under a state lock. In addition, Move the work from the global WQ to mlx5e WQ to make sure this work is flushed when device is detached.. Also, move the mlx5e_tx_timeout_work code to be next to the TX timeout NDO for better code locality.

2018-03-27IB/core: Refer to RoCE port property to decide building cacheParav Pandit
IB core maintains the GID cache entries for the GID table. This cache table has to be maintained regardless of HCA's support of GID table. For IB and iWarp ports, cache is created by querying the HCA. For RoCE cache is created based on netdev events. Therefore just refer to the RoCE port property of the {device, port} to decide whether to build cache by querying HCA or from netdev events. There is no need to check if HCA support GID table or not. ib_cache_update() referred to RoCE attribute before validating port. Though in all current callers port is valid, it is incorrect to query RoCE port property before validating the port. Therefore, rdma_protocol_roce() check is done after rdma_is_port_valid() verifies that port is valid.
