First of all, it exposes the SKB list implementation. Second of all it's not needed. If we get called here, we successfully enqueued the URB with the linked SKB and such a completion only gets called one time on such an SKB. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg2-46/+35
The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

2009-04-22rtl8187: Implement TX/RX blink for LEDLarry Finger5-4/+298
The following patch implements some control over the LED on RTL8187B and RTL8187L devices. Triggers are registered for TX and RX. Whenever the trigger event occurs, the LED is turned off for 1/20 second, then turned back on. Note: For those RTL8187X devices that are built into the computer and have a LED that is expected to be controlled with a radio switch, this patch will not operate that LED. That will take a separate patch to be prepared later.

This message appears to be nothing more than a leftover of the experimental-8187B era. Also, we print the HW type in the hwaddr line, making this message reduntant.

2009-01-29rtl8187: Fix driver to return TX retry info for RTL8187LLarry Finger2-19/+58
Current code for the RTL8187 is not returning valid retry information, thus the rate-setting mechanism is not functioning. As a further complication, this info is only obtained by reading a register, which cannot be read while in interrupt context. This patch implements the TX status return to mac80211 through the use of a work queue. One additional problem is that the driver currently enables the rate fallback mechanism of the device, which conflicts with the mac80211 rate-setting algorithm. This version of the patch disables rate fallback.

2009-01-29rtl8187: Fix error in setting OFDM power settings for RTL8187LLarry Finger1-2/+8
After reports of poor performance, a review of the latest vendor driver (rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken. A difference was found in the code used to index the OFDM power tables. When the Linux driver was changed, my unit works at a much greater range than before. I think this fixes Bugzilla #12380 and has been tested by at least two other users.

2009-01-12rtl8187: Fix module so that rmmod/insmod does not errorJohannes Berg1-2/+3
Due to misunderstanding of the returned values allowed for the tx callback of mac80211, rtl8187 was using skb's that had been freed. This problem was triggered when the module was sujected to a rmmod/insmod cycle. After that was fixed, the modules would not work after the rmmod/insmod cycle until the USB device was reset.

2008-12-19rtl8187: Fix crash on unload when using SLUB debugHerton Ronaldo Krzesinski1-8/+4
Reported-by: Hin-Tak Leung <htl10@users.sourceforge.net> After the code was modified to use urb anchors ("rtl8187: Use usb anchor facilities to manage urbs"), rtl8187 began generating an intermittent GPF on shutdown when using SLUB with debugging enabled. Furthermore, rebooting the system with a ping running caused a GPF every time. There are two problems: (1) incorrect locking in the rtl8187_rx_cb() routine, a pre-existing bug that apparently had not been triggered before, and (2) duplicate freeing of receive skbs that was probably introduced with the change to anchors.

2008-12-12rtl8187: Use usb anchor facilities to manage urbsLarry Finger2-25/+52
When SLUB debugging is enabled in the kernel, and the boot command includes the option "slub_debug=P", rtl8187 encounters a GPF due to a read-after-free of a urb. Following the example of changes in p54usb to fix the same problem, the code has been modified to use the usb_anchor_urb() method. With this change, the USB core handles the freeing of urb's. This patch fixes the problem reported in Kernel Bugzilla #12185 (http://bugzilla.kernel.org/show_bug.cgi?id=12185).

2008-12-12rtl8187: Improve wireless statistics for RTL8187Larry Finger1-34/+15
The current wireless statistics for the RTL8187 poorly indicate the signal strength and quality. With testing, I found that the AGC value is inversely correlated with the strength as in the RTL8187B. By implementing a similar calculation, much more code becomes common to the two devices.

I mistakenly changed retry count passed in rtl8187_tx in previous change "rtl8187: feedback transmitted packets using tx close descriptor for 8187B". For 8187 it should represent the number of retries (retry count limit). As explained by Johannes Berg, .count represents the number of tries (not retries), and retries = tries - 1.

2008-11-25rtl8187: feedback transmitted packets using tx close descriptor for 8187BHerton Ronaldo Krzesinski2-4/+136
Realtek 8187B has a receive command queue to feedback beacon interrupt and transmitted packet status. Use it to feedback mac80211 about status of transmitted packets. Unfortunately in the course of testing I found that the sequence number reported by hardware includes entire sequence control in a 12 bit only field, so a workaround is done to check only lowest bits.

Hin-Tak Leung reported that after the change "rtl8187: add short slot handling for 8187B" his RTL8187B started to give low throughput on network transfers. Turns out that the SIFS setting used isn't ok, it doesn't look to be the real aSIFSTime, using the "magical" 0x22 value like on other 818x variants as the vendor does too fixes the issue.
