How to use wifi on hp stream11?

[Semme]

I can't get Bionicpup64 to work on my system because the wifi card won't work. It works with the b43 pci module on 32b.

Via PM Ali went with my hunch that BP64 wants the Broadcom wl driver.

03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

In the process the ssb, bcma, b43, b44 & brcmsmac modules were blacklisted:
the "wl_apsta.o" firmware from this pkg extracted to /lib/firmware.

After a quick reboot -- "Houston, we have an interface!"
