The lack of support in b43 for modern phys such as AC, i.e. the gap between b43 and brcmfmac, is extremely annoying and turning perfectly fine aftermarket devices into paperweights because there isn't even a way to make Broadcoms old proprietary blob work with contemporary kernels. If Broadcom could be convinced to either add support for the late b43 variants or at least release documentation for the aftermarket that would be great. I suppose they might be coming to the conference so give them my best regards with a "please fix" tag attached. Yours, Linus Walleij
