Currently, even though FLUSH CFG is all set, the LLC does not enter bypass mode.
In axi_llc_config.sv, conf_regs_i.flushed is never completely set to 1, so the bypass mode is never activated.
This is because the FSM is not doing the last flush iteration.
With these changes, this is fixed and bypass mode is activated when setting all bits of FLUSH CFG.
