That's ok. Let's go back to small steps now.

We have cyclic rmmod/insmod working, and that's good: it means there's
no hw issue.

The next step to have working now is really the ifconfig up/down/up
scenario. That should come before suspend/resume. And this
step-by-step approach is even more relevant to libertas_sdio, because
I suspect there's some if_sdio.c refactoring needed to get it right,
but let's see.

The expected result you want to get is:

- boot, power is off
- insmod, power is still off
- ifconfig up, power is on
- ifconfig down or rmmod, power is back off
