How can we tell whether "ipw2x00" is driver or firmware? * I check wiki: https://en.wikipedia.org/wiki/Comparison_of_open-source_wireless_drivers * It seems that "ipw2x00" IS a driver, right?
* (And logically, we should not be required to select firmware, right?) * (I mean: logically, if we select the driver, yocoto should select corresponding firmware automatically for us, right?) Thanks!
