And that's been my plan from day one... which is remarkably a lot like
the behavior of several net drivers. :)
* attempt to read WWN during module load
* admin may optionally choose to manually specify OR auto-generate a WWN
* fail, if no WWN [stating the obvious]
And like with networking cases, we have situations where a platform
might be able to assist.
There are several systems that provide a "system MAC address"
to use when you can't obtain one for a specific device. This
valus is provided via a firmware property.
Similarly, we could ask an interface that goes to platform to
ask them for a WWN.
Good point -- I bet I will run into this when I get a Broadcom HT-1100
test system, which is the on-board version of the board supported by my
new 'broadsas' driver.
