e6ac9f6006 RDMA/mlx5: Enable sniffer when device is in switchdev mode 
In order to allow sniffer when the RDMA device is in switchdev mode, we
don't need to set the source port when creating the sniffer rule.

d6673746d6 RDMA: Remove constant domain argument from flow creation call 
The "domain" argument is constant and modern device (mlx5) doesn't support
anything except IB_FLOW_DOMAIN_USER, so delete this extra parameter and
simplify code.

23fcc7dee2 RDMA/mlx5: Fix flow destination setting for RDMA TX flow table 
For RDMA TX flow table, set destination type to be 'port' and prevent
creation of flows with TIR destination.

As RDMA TX is an egress flow table the rules on this flow table should
not forward traffic back to the NIC and should set the destination to be
the port.

Without the setting of this destination type flow rules on the RDMA TX
flow tables are not created as FW invokes a syndrome for undefined
destination for the rule.

When using action drop dest_type was never assigned to any value.  Add
initialization of dest_type to -1 since 0 is valid.

fs.c because it is better describe the content.
