As soon as skb is ready to be reaped, prefetch 1-st cache line. This accelerates data access that is performed later, during the packet classification by the driver and IP stack. Signed-off-by:

Use hardware capabilities to limit IRQ generation to about 15 per msec It corresponds to about 7 packets/IRQ when running iperf with default parameters at 1.3Gbps Do not enable this feature in the sniffer (monitor) mode, because interrupt moderation cause timestamp accuracy deterioration. For the sniffer flow, it is important to get precise timestamp. Signed-off-by:

The firmware doesn't support per packet encryption selection, so disable hw encryption support completely while a monitor interface is present to support injection of packets (which shouldn't get encrypted by hw). To enforce the changed hw encryption support force a disassociation on non-monitor interfaces. For disassociation a workaround using hw connection monitor is employed, which temporary enables hw connection manager flag. Signed-off-by:

Use the ENABLE_RX command for channel switching when no interface is present (monitor mode only). The advantage of ENABLE_RX is that it leaves the tx data path disabled in firmware, whereas the usual JOIN command seems to transmit some frames at firmware level. Signed-off-by:

With a dissasociated card I often encoutered very long scan delays. My guess is that it has something to do with the cards DTIM handling and another firmware bug mentioned in the TI WLAN driver, which is described as the card may never end scanning if the channel is overloaded because it can't send probe requests. I think the firmware somehow also tries to receive DTIM messages when the BSSID is not set. Therefore most of the time it waits for DTIM messages and can't do scanning work. Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY bit for scans in disassociated state. Signed-off-by:

This patch fixes two regressions introduced with the recent rfcomm tty rework. The current code uses the carrier_raised() method to wait for the bluetooth connection when a process opens the tty. However processes may open the port with the O_NONBLOCK flag or set the CLOCAL termios flag: in these cases the open() syscall returns immediately without waiting for the bluetooth connection to complete. This behaviour confuses userspace which expects an established bluetooth connection. The patch restores the old behaviour by waiting for the connection in rfcomm_dev_activate() and removes carrier_raised() from the tty_port ops. As a side effect the new code also fixes the case in which the rfcomm tty device is created with the flag RFCOMM_REUSE_DLC: the old code didn't call device_move() and ModemManager skipped the detection probe. Now device_move() is always called inside rfcomm_dev_activate(). Signed-off-by:

This patch fixes a userspace regression introduced by the commit 29cd718b. If the rfcomm device was created with the flag RFCOMM_RELEASE_ONHUP the user space expects that the tty_port is released as soon as the last process closes the tty. The current code attempts to release the port in the function rfcomm_dev_state_change(). However it won't get a reference to the relevant tty to send a HUP: at that point the tty is already destroyed and therefore NULL. This patch fixes the regression by taking over the tty refcount in the tty install method(). This way the tty_port is automatically released as soon as the tty is destroyed. As a consequence the check for RFCOMM_RELEASE_ONHUP flag in the hangup() method is now redundant. Instead we have to be careful with the reference counting in the rfcomm_release_dev() function.

The destructor for net devices was set to free_netdev() to get rid of it and the private data. The private data refers to a brcmf_if instance, but indirectly it also refers to brcmf_cfg80211_vif which holds the wdev. This is freed as well by using a new custom destructor called brcmf_cfg80211_free_netdev(). Reviewed-by:

The wiphy_unregister() call was done in brcmf_free_vif() when the last interface was being removed. This is not the obvious place to do that. This patch moves it to the brcmf_cfg80211_detach(). This removes the need to keep count of interfaces. Reviewed-by:
