* staging: r8712u: Most return-values changed from -1 to proper errno macros.Ali Bahar2011-09-061-22/+22
| | | | | | | | | | | | | The ioctl handlers were frequently returning -1 upon failure. Most of these have now been changed to proper errno macros. The few remaining ones have been left untouched because either the handler is not called (and so cannot be tested), or the function never fails (and so cannot be system-tested), or requires new code to distinguish its failures.

* staging: r8712u: Merging Realtek's latest (v2.6.6). Various fixes.Ali Bahar2011-09-061-6/+138
| | | | | | | | | | | | | | | | | | passive_mode added to private ioctls. New private ioctls added for RSSI, link speed, mac address, scan type, and DCE-D. In r8711_wx_get_scan(), we now sleep only 100 times, instead of 1000. In r8711_wx_set_essid(), added a check for Ad-Hoc state. In r8711_wx_get_rate(), added a check for RTL8712_RF_2T2R RF type. Added Set chplan. In r871x_get_wireless_stats(), updated the mechanism for displaying link quality. Added SetDIG and SetRA commands. r8712_joinbss_cmd() no longer checks for Ad-Hoc mode.

* staging: r8712u: Merging Realtek's latest (v2.6.6). Updated include directives.Ali Bahar2011-09-061-0/+9
| | | | | | | | | | | | These are the new include directives for header files. The following were (somehow!) not explicity in Realtek's, but proved necessary: "linux/usb.h" is needed for usb_alloc_urb(); "linux/interrupt.h" is needed for tasklet_struct. It was often a nested include. Signed-off-by: Ali Bahar <ali@internetDog.org> Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* rtl8712: don't just return -EFAULT in wpa_supplicant_ioctl()Dan Carpenter2011-08-231-1/+2
| | | | | | | | | There were some curly braces missing so the original code in wpa_supplicant_ioctl() pretty much always returned -EFAULT without doing anything. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* staging: r8712u: Sets to SSID, and to AP MAC#, can now be done when the ↵Ali Bahar2011-08-231-4/+21
| | | | | | | | | | | | | | | | | | interface is Down. The original Realtek code assumed that ioctl Sets get done after the interface is Up. This included the set to Essid and to the AP MAC#; and it fit Realtek's installation procedure. But there is no such necessity for the adapter, and no stated requirement found elsewhere. Also, wireless drivers typically permit this. A typical error message used to be: Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Operation not permitted.

* Staging: rtl8712: fix math errors in snprintf()Dan Carpenter2011-02-091-9/+13
| | | | | | | | | | | | | The original code had calls to snprintf(p, 7, "wpa_ie=") but that string is 8 characters (because snprintf() puts a NUL terminator on the end). So instead of an '=' the what gets written to buf is a NUL terminator followed by the rest of the string. And actually the %02x formats are three chars as well when you include the terminator.

This code is for a completely new version of the Realtek 8192 USB devices such as the D-Link DWA-130. The Realtek code, which was originally for Linux, Windows XP and Windows CE, has been stripped of all code not needed for Linux. In addition, only one additional configuration variable, which enables AP mode, remains.
