Subject: [PATCH 04/15] mlx5: Use refcount_t for refcount
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.

Subject: [PATCH 12/15] net/mlx5: Add per-namespace flow table default miss
action support
Currently all the namespaces under the same steering domain share the same
default table miss action, however in some situations (e.g., RDMA RX)
different actions are required. This patch adds a per-namespace default
table miss action instead of using the miss action of the steering domain.

Subject: [PATCH 13/15] net/mlx5: Create bypass and loopback flow steering
namespaces for RDMA RX
Use different namespaces for bypass and switchdev loopback because they
have different priorities and default table miss action requirement:
1. bypass: with multiple priorities support, and
MLX5_FLOW_TABLE_MISS_ACTION_DEF as the default table miss action;
2. switchdev loopback: with single priority support, and
MLX5_FLOW_TABLE_MISS_ACTION_SWITCH_DOMAIN as the default table miss
action.
