So this is device with BCM4335 chipset which is a FullMAC one AFAIK.
It may be supported by brcmfmac. There is already support for BCM4335
in brcmfmac but it was developed for SDIO devices only. I don't think
we ever met BCM4335 on PCIe device.

You may try:
sudo su
rmmod bcma
echo "14e4 43ae" > /sys/bus/pci/drivers/brcmfmac/new_id
dmesg | grep brcmfmac

However I think brcmfmac may need some extra changes to support
BCM4335 on PCIe. Lets also see if Broadcom team can help us with this.

It does have an ARM core, but for fullmac we need RAM as well and I
don't see that listed. So I guess it is a 43162 and needs softmac
driver. Also could not find any fullmac firmware for it. The only thing
I found was a hybrid wl driver release for it.
