hostap and sleeping mode.

Hi all,

ok here are some new issues about hostap and sleeping mode.
Now hostap works when resuming from sleeping also in host_roaming 2.
I have two different problems with hostap 0.0.4 and 0.1.3. With the first,
everytime I resume from sleeping, the hostap driver does not get unloaded
and with the "lsmod" command the hostap_cs module appears to be used
3,4,5,6, etc times (once for each time that the laptop went to sleep).
With hostap 0.1.3 the same thing happens, but this time the number is
negative -2, -3, -4, etc.
You guys have any clue why this would happen??? How do I fix it? Sounds
like it could be a cardmgr issue.
The second question I have is about hostap 0.0.4. In the file hostap.c
there are two pointers: dev->stop and dev->open. Who uses these two
pointers? Where are they called? I need to know this because in order to
make hostap resume from sleeping, I had to comment out the dev->stop
pointer assignment. (The card would close right after the sleeping event
was captured so that nothing else would work for resuming).
I suspect the two pointers are used by the card manager, but I could not
find where.

Thank you everyone,
