Hi,

we are using wpa_supplicant 2.3 and libnl 3.2.25 in combination with a 
WL1271 device on a i.MX28.

We encounter something strange errors.
All works well and stable but a soon as we have a AP with a TKIP cypher, 
we get an error:

Failed to set PTK to the driver (alg=2 keylen=32 bssid=00:11:50:7d:05:c0)

If we enable the debug we see:

===========================
