wpa_supplicant : Association request to the driver failed

[lijinlei1]

Hi Dan,

Thanks for your reply.
I am using the 2.6.24 stock kernel from kernel.org, and i.MX31L (3-stack) platform. I applied the freescale patch to get the SDIO working.
I tried 2 options: 2.6.24 libertas (from stock kernel) + v8.73 firmware (from Marvell), not work.
                   2.6.27 libertas (from stock kernel) + v9.70 firmware (from Marvell), still no luck.

The logs from wpa_supplicant 0.6.9 are the same for the 2 options above.
I traced the call sequences, I found in wpa_driver_wext_associate():

line 2096:
 if (wpa_driver_wext_set_auth_param(drv,
        IW_AUTH_PRIVACY_INVOKED, value) < 0)
  ret = -1;
and line 2111:
 if (wpa_driver_wext_set_auth_param(drv,
        IW_AUTH_RX_UNENCRYPTED_EAPOL,
        allow_unencrypted_eapol) < 0)

Those 2 calls failed. The libertas driver can't handle those 2 ioctls: IW_AUTH_PRIVACY_INVOKED and IW_AUTH_RX_UNENCRYPTED_EAPOL, with value 10 and 8 respectively.
Will this be the cause of the association failure?
Thanks.
