From a0f6d6caef4033aa9c3e2ea2ceae256c4347a419 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Fri, 24 Feb 2012 21:36:05 -0800 Subject: mwifiex: handle auto authentication mode correctly When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC, driver tries to connect using open mode. The association is failed if AP is configured in shared mode. This patch adds code to try association using shared mode as well if open mode association fails. Now since we returned exact error code in association response handler (instead of -1), corresponding changes are done in mwifiex_process_cmdresp().

When wpa_supplicant provides valid SSID list followed by zero-length SSID for wildcard scan, only specific SSID scan is performed by driver. Actually driver is expected to do both type of scanning in this case. The patch fixes this issue. Also, use SSID list pointer provided by stack directly, instead of copying SSID's to local structure.

This works on little endian systems but not on big endian ones. I've changed mwifiex_drv_change_adhoc_chan() to use a 16 bit variable. This matches the other functions in the file. I considered changing mwifiex_change_adhoc_chan() as well but it turns out that the function isn't implemented so I just removed the definition.
