2019-08-07mlx5: Use refcount_t for refcountChuhong Yuan3-7/+8
Reference counters are preferred to use refcount_t instead of atomic_t. This is because the implementation of refcount_t can prevent overflows and detect possible use-after-free. So convert atomic_t ref counters to refcount_t. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Acked-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2019-08-05rdma: Enable ib_alloc_cq to spread work over a device's comp_vectorsChuck Lever7-20/+68
Send and Receive completion is handled on a single CPU selected at the time each Completion Queue is allocated. Typically this is when an initiator instantiates an RDMA transport, or when a target accepts an RDMA connection. Some ULPs cannot open a connection per CPU to spread completion workload across available CPUs and MSI vectors. For such ULPs, provide an API that allows the RDMA core to select a completion vector based on the device's complement of available comp_vecs. ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted to use the new API so that their completion workloads interfere less with each other.

2019-08-01net/mlx5: E-switch, Tide up eswitch config sequenceParav Pandit3-25/+41
Currently for PF and ECPF vports, representors are created before their eswitch hardware ports are initialized in below flow. mlx5_eswitch_enable() esw_offloads_init() esw_offloads_load_all_reps() [..] esw_enable_vport() However for VFs, vports are initialized before creating their respective netdev represnetors in event handling context. Similarly while disabling eswitch, first hardware vports are disabled, followed by destroying their representors. Here while underlying vports gets destroyed but its respective user facing netdevice can still exist on which user can continue to perform more offload operations. Instead, its more accurate to do enable_eswitch switchdev mode: 1. perform FDB tables initialization 2. initialize hw vport 3. create and publish representor for this vport disable_eswitch switchdev mode: 1. destroy user facing representor for the vport 2. disable hw vport 3. perform FDB tables cleanup Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
