Ubuntu 15.04 - Macbook Pro Early 2015 (12,1) no 5 GHz wireless

[Jrddvs]

Fresh install of 15.04 on a Macbook Pro 12,1.

>Network controller [0280]: Broadcom Corporation BCM43602 802.11ac Wireless LAN SoC [14e4:43ba] (rev 01)

I copied brcmfmac43602-pcie.bin (https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/brcm/) into /lib/firmware/brcm which enabled the wireless to pick up some SSIDs, but not all (almost positive the only ones seen are 2.4GHz).

I was referred to this document: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

Then I ran:

$ lspci -vvnn | grep -A 9 Network

I find the PCI device ID here: https://wireless.wiki.kernel.org/en/users/Drivers/brcm80211#brcmfmac (Chipset BCM43602, ID: 14e4:43ba)

I dropped the relevant firmware files from the repo given a bit further down that page (repo: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/brcm) into /lib/firmware/brcm/

...still no 5 GHz.

Installed on a late 2014 Macbook pro, same chip, same issue with 15.04. Worked fine with 14.04
