Since we do not currently report HT rates (MCS index) in radiotap header for HT rates, we should not claim the rate is present. The rate octet itself is used as padding in this case, so only the it_present flag needs to be removed in case of HT rates.

Reported-by: NHin-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.

This patch simplifies the tx code a bit and will be necessary for the upcoming stlc45xx<->p54 port. In detail: we no longer have to tell all back-end drivers directly, if we want to free a frame right after it was send to the firmware, or if we do it in the library callback later.

This patch moves a good chunk of code from the former statistic update timer routine into a workqueue, which is kindly provided by mac80211. Also as a nice side-effect we can lay the foundation for other essential housekeeping features we want to do in the future. e.g: - drain the (clogged) tx_queue. - initiate bursts.

When a STA roams back to the same AP before the previous STA entry has expired, a new STA entry is not added in mac80211. However, a Layer 2 Update frame still needs to be transmitted to update layer 2 devices about the new location for the STA. Without this, switches may continue to forward frames to the previous (now incorrect) port when STA roams between APs.

open() routine calls stop() in case of errors, the function will try to free the requested IRQ. But we don't know if it was actually requested, so the code might issue bogus free_irq(0, dev) call. Fix this by rearranging the code so that now request_irq() is the last call in the open() routine, and move free_irq() into the close().

The timeout handling code is currently broken in several ways: - It calls stop() (which frees all the memory and IRQ), and then calls startup() (which won't re-request IRQ, neither it will re-init the Fast UCC structure). - It calls these routines from the softirq context, which is wrong, since stop() calls free_irq() (which might sleep) and startup() allocates things with GFP_KERNEL. - It won't soft-reset the PHY. We need the PHY reset for at least MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover from timeouts w/o the reset. So the patch fixes these problems by implementing the workqueue for the timeout handling, and there we fully re-open the device via close() and open() calls. The close/open paths do the right things, and I can see that the driver actually survive the timeouts. Signed-off-by: NAnton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: NDavid S.

Currently the routines wait for the various bits w/o an assumption that bits may never get set. When timeouts happen I see that these bits never get set and so the routines hang the kernel. With this patch we'll wait the graceful stop for 100 ms, and then will simply exit. There is nothing* we can do about that, but it's OK since we'll do full reset later. * Well, actually, there is also not-graceful variant for the TX stop, but specs says that we never should use it.

Implementing discard counters for the NIU driver turned out to be more complicated than first assumed. The discard counters for the NIU neptune chip are only 16-bit (even though this is a 64-bit chip). These 16-bit counters can overflow quickly, especially considering this is a 10Gbit/s ethernet card. The overflow indication bit is, unfortunatly, not usable as the counter value does not wrap, but remains at max value 0xFFFF. Resulting in lost counts until the counter is reset. The read and reset scheme also poses a problem. Both in theory and in practice counters can be lost in between reading nr64() and clearing the counter nw64(). For this reason, the number of counter clearings nw64() is limited/reduced. On the fast-path the counters are only syncronized once it exceeds 0x7FFF. When read by userspace, its syncronized fully.

A major source of overhead in the enc28j60 driver is the SPI transfers. Each SPI transfer entails two kernel thread context switches. One major source of SPI transfers is the enc28j60_set_bank() functions which runs before every register access. This patch reduces the number of SPI transfers that enc28j60_set_bank() performs in two ways: 1. removes unnecessary bank switch for the registers that are present in all banks 2. when switching from banks 0 or 3 to banks 1 or 2 (i.e. only one bit changes) enc28j60_set_bank() does only one SPI transfer instead of two According to my tests these changes reduce the number of SPI transfers in about 25%.
