The tech forum is password protected, so no direct link ATM. In fact
wasn't it stated earlier in the thread that:

In any case, there are larger problems. The driver internally talks to
the chip e.g. to download the firmware patch. When running against
UF6026 (a fairly common 2 year old n-wireless core from CSR), it
complains:
UniFi f/w protocol major version (8) is different from driver (v9.1).
Three things about this:
1) You'd think the f/w protocol would be at least slightly
backwards-compatible (sigh).
2) The driver probe should check for an unsupported hwids and blacklist them.
3) UF60xx series are not really old and yet this driver seems to be
based on the newer CSR software for UF80xx, so it cannot really be
called "CSR" driver. Perhaps "CSR8000 driver"?
