Subject: [PATCH net-next 4/7] mlxsw: Propagate extack to mlxsw_afa_block_commit()
In the following patch, attempts to change the next/goto of a flexible
action set from goto to next will be rejected for action sets that contain
a trap_fwd action. Propagate extack to make it possible to communicate the
issue to the user.
