I'm trying to add BCM43526 support. This chipset can be found in:
1) Some USB dongles, e.g. Tenda W900U uses revision 2
2) Some routers, e.g. Asus RT-AC53U uses revision 3+
Unfortunately attached patch doesn't seem to be enough, brcmfmac doesn't
work with my Tenda W900U. I keep getting following error:
brcmfmac: brcmf_usb_recv_ctl Enter
brcmf_usb_rx_ctlpkt: rxctl wait timed out
brcmfmac: brcmf_fil_cmd_data Failed: -5
It seems that:
1) driver sends TX URB and gets completion callback called
2) driver sents RX URB but it never gets completed
Unfortunately this device is a BMAC device. You can tell by the 'high' word
in the windows driver name. So there is no chance whatsoever to get this
device going with brcmfmac.
Oh damn, I was sure Broadcom dropped this design back in BCM43236
times, I didn't even suspect newer chipsets may be still using it :(
Shit.
Apparently this design is still in demand by our customers against all
hopes.
Do you have any idea about BCM43526 rev 3+? The chipsets using 43526b
instead of 43526a. Any chance BCM43526 rev 3+ is normal FullMAC device
just like BCM43236 rev 3+?
I don't know. Main thing needed for that is more on-chip memory, which
makes it a bit more expensive. This may be a deal breaker for existing
43526 customers unless they like the fullmac advantages they get for
their money.
