Hi,
i am trying to implement on a smart city network a solution based on high end home routers like the asus RT-AC66U.
we want to use openwrt for that but unfortunately the broadcom driver isn't yet supported.
I have one rt-ac66u here for development, there is anything that i can do for help?
i came here after a suggestion of one member on openwrt forum:
https://forum.openwrt.org/viewtopic.php?pid=217341#p217341

i also read this past email:

Thx for attention.

Not sure what 11ac chipset is used. The upstream brcm80211 drivers currently only support one 11ac chipset, ie. the bcm4335. This is a single stream with SDIO host interface supported by the fullmac driver brcmfmac.

For chipsets like 4360 we need to add AC phy support to brcmsmac. So far we do not have green light to do so.

Arend

Hiya,

Is this still the status quo? I'd like to start porting updated broadcom support to FreeBSD for Apple Macintosh users who would like 11ac NIC support.

Hi Adrian,

Interesting. A while ago someone wanted to port brcmsmac to a BSD flavor (not sure which one). Now brcmsmac as-is today uses BCMA bus driver which goes under GPL-v2, which may or may not be a problem. Apple Mac users probably have 4360 and that hurdle is also still there.
