When HW Steering is enabled, mlx5dr translates flow items using DV
item translation functions to configure flows in root flow table.
Represented port item stores vport metadata tag in thread-local
workspace when translate to DV spec. Due to the thread-local workspace
was not created in HW Steering, it caused an assertion in
mlx5_flow_get_thread_workspace()
This patch adds initialization of thread-local workspace when flow items
are translated to DV spec in HW Steering mode.
Fixes: cfddba76af4f ("net/mlx5: add hardware steering item translation
function")
