Trying to add support of 802.11ac broadcom chpiset to openwrt

Trying to add support of 802.11ac broadcom chpiset to openwrt

[Alessandro Gnagni]

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:
http://www.spinics.net/lists/linux-wireless/msg110443.html

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.

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.
