Whether it will run in this case will depend on whether or not the firmware was needed or not, if it was it won't. Note that there is a FW API call which implies "this is optional firmware", its the request_firmware_direct() call but this call is synchronous, we have no option for asynchronous behaviour. I intend to add support for that but that requires a bit of changes. Also, based on my review its a fair assumption that most calls to the FW APIs mean they need it. The only ones we can be sure are optional are the ones using request_firmware_direct(). > Don't > expect us to care about the issues you run into.

Yeah sure, we even let your system go out of regulatory compliance, see CFG80211_CERTIFICATION_ONUS, and CFG80211_REG_CELLULAR_HINTS. Then with CFG80211_INTERNAL_REGDB the parser right now lacks support for a few new bells and whistles and requires expert knowledge how to properly build and integrate all new bells and whistles. It seemed folks were OK with this.
