   He leah,
   Yes, you are right. Changing that byte makes no difference to wifi.

     I made some changes to ich9gen, relating to the descriptor, some
     ago. We found for instance that the "component density" section was
     wrong, so we fixed that. There were some other minor changes. Users
     have reported working wifi with those newer descriptors in earlier
     snapshots. The 96 snapshot uses a new revision of coreboot and as
     as I know, this is all that has changed, aside from some minor
     changed which also shouldn't (in my opinion) affect wifi. We think
     upstream (coreboot project) might have broken it, so someone will
     to bisect coreboot to see if there is a regression, and if so on
