Oh, it was never my intention to say such blasphemy :)
It meant to be just a debug option to help the users, specifically the
ones debugging drivers, to try using a hammer to recover bad devices! To
this issue that I mentioned as an example, the fix specifically goes in
the FW of the adapter.

Anyway, since you really dislike it, let's drop it, no big deal!
