You're right that `txsim` has no clear supported use case. It enables the TX
path on hardware that reports no TX capability and uses a timer to fake TX
completion, while the samples are still written to the hardware TX output
registers. I have not found evidence that this provides reliable transmission
on such hardware.

I'll remove the `txsim` parameter and its timer-based simulation path while
keeping native TX support for hardware that reports the capability. This also
removes the timer lifecycle issue, so I will revise the patch to remove the
unsupported simulation path instead of keeping a standalone timer fix.

Thanks,
