Cc'ing a few lists for wider review given that what we had written before for rules was for 802.11 and Bluetooth [0] and it was very Linux specific. We are striving for open firmware here for the community, for BSD / Linux. Christian would have dealt with more of the support on open firmware design so far due to carl9170.fw [1] so curious if he has any input. As for 802.11 the rules we defined were pretty silly about firmware file names but should be considered. Here's the key thing I think we should keep from those old guidelines: "In general if you are just providing bug fixes you do not need to provide a new firmware filename for the module, using the old filename is fine so long as the same API was kept." The rest I think your specification details better what we should do in terms of API changes for versioning.
