I would think that "> [ 8.034053] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 12, Type 11 (AC), Revision 1)" would be self explanatory. Obviously, b43 does not support that device, and I doubt that it ever will. Reverse engineering 802.11g was difficult, 802.11n was much harder, and I suspect that 802.11ac would be impossible.
Your only option is to use the Broadcom hybrid (proprietary) driver. It will taint your kernel, and we do not support it here, but it is your only choice.
