Revert "net/mlx5e: Don't use termination table when redundant"
This reverts commit 14624d7247fcd0f3114a6f5f17b3c8d1020fbbb7.
The termination table usage is requires for DMFS steering mode as firmware
doesn't support mixed table destinations list which causes following
syndrome with hairpin rules:
[81922.283225] mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 25977): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xaca205), err(-22)
Fixes: 14624d7247fc ("net/mlx5e: Don't use termination table when redundant")
