From: Parav Pandit <parav@mellanox.com>
Flow steering core layer is independent of the eswitch layer.
Hence avoid fs_core dependency on eswitch.
Fixes: 328edb499f99 ("net/mlx5: Split FDB fast path prio to multiple namespaces")

From: Tariq Toukan <tariqt@mellanox.com>
Add explicit WQE segment structures for the TLS static and progress
params.
According to the HW spec, TISN is not part of the progress params context,
take it out of it.
Rename the control segment tisn field as it could hold either a TIS or
a TIR number.
