I suggest you look at bcm43xx-mac80211.
You will need to introduce refcounting for your monitor interfaces
and I _really_ suggest to get rid of the zd_op_open() and zd_op_close()
functions. Just include that in add/remove interface. You need
to refcount your interfaces anyway.

I don't know what you mean by hard/soft monitor.

Don't care about the id_id. It's a cookie and it's opaque to
the driver.

Semantics are pretty easy for add/remove interface. The function
is called every time the user adds/removes an interface. :)
