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.
