Are you aware, that b43's code comes from RE efforts and PHY part is mostly identical to brcmsmac/wl's one? We have the same functions, conditions, operations here. Sometimes called in a different way, sometimes we have different code structures, but generally code is the same. So I still don't see the advantages of using brcmsmac instead of b43. > The driver is fully supported by Broadcom, and provides an API for addition of > phy support for newer chipsets that will help speed up the process of getting > support for those chipsets into the kernel. I'm glad you're so proud of yours flexible API, but b43 has the same implemented since 2008. You can see we've just easily added support for HT-PHY using our API and I'm working on LCN-PHY right now (without modifying the API). We would like to have b43 supported by Broadcom. It sounds much better, I've shown you a lot of advantages of such a choice. Switching to brcmsmac on the other hand needs a lot of work and improvements. -- Rafał _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
