* rtlwifi: rtl8192cu: remove check for CONFIG_AUTOSUSPENDPaul Bolle2014-05-29
| | | | | | | | | A check for CONFIG_AUTOSUSPEND was included in this driver when it was added in v2.6.39. But that Kconfig symbol doesn't exist. Remove that check and the single line it hides. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbbLarry Finger2014-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beginning with kernel 3.13, this driver fails on some systems. The problem was bisected to: Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau <nbd@openwrt.org> Title: mac80211: send control port protocol frames to the VO queue There is noting wrong with the above commit. The regression occurs because V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to modify the rtl8192se routine that sets the correct transmit queue.

| | | | | | | | | | | | | | | | | | Add MSI interrupts mode support, enable it when submodules' msi_support flag is true, also could fallback to pin-based interrupts mode if MSI interrupts mode fails. RealTek's policy(on modules which work well with MSI interrupts mode) is: > If the platform supports both MSI and pin-based, use MSI. > If the platform supports MSI only, use MSI. > If the platform supports pin-based only, use pin-based.

[Q]-0 (stream=0, delta=15903, new_hw_ptr=293408, old_hw_ptr=277505) The exact code flow that causes that is: 1. wpa_supplicant send a start_scan request to the nl80211 driver 2. mac80211 module call rtl_op_config with IEEE80211_CONF_CHANGE_IDLE 3. rtl_ips_nic_on is called which disable local irqs 4. rtl92c_phy_set_rf_power_state() is called 5. rtl_ps_enable_nic() is called and hw_init()is executed and then the interrupts on the device are enabled A good solution could be to refactor the code to avoid calling rtl92ce_hw_init() with the irqs disabled but a quick and dirty solution that has proven to work is to reenable the irqs during the function rtl92ce_hw_init(). I think that it is safe doing so since the device interrupt will only be enabled after the init function succeed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 0baa0fd76f3f5a134461d6cf30294f6bb1bb824c ("rtlwifi: Convert core routines for addition of rtl8192se and rtl8192de") removed setting HW_VAR_RCR, HW_VAR_MGT_FILTER and HW_VAR_CTRL_FILTER. The last two are probably done because some hardware does not support them. The first is probably a mistake. This patch adds the missing set_hw_reg call. For PCI support, rx_conf is not touched directly. Instead, get_hw_reg is used to abstract between receive_config (for PCI) and rx_conf (for USB). This was tested on a 10ec:8176 Realtek RTL8188CE (according to the label on the mini-PCIe card). Before this patch, `iw wlan0 set monitor otherbss` did not capture frames from other BSS's. After this patch, it does print packets.

* | rtlwifi: avoid accessing RCR directlyPeter Wu2014-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtl*_set_check_bssid functions are mostly the same, but access the RCR register in different ways. Use the get_hw_reg abstraction layer (which reads rtlpci->receive_config for PCI devices and mac->rx_conf for USB). There is no functional change for cases where receive_config was accessed directly. For rtl8192ce, there is still no change because nothing modifies REG_RCR or receive_config. For rtl8192cu, it now also applies changes to rx_conf from configure_filter, but that can be considered a bug which is fixed later.

| | | | | | | | | | | | | | | | | | | | | | A few places weren't checking that the frame passed to the function actually has enough data even though the function clearly documents it must have a payload byte. Make this safer by changing the function to take an skb and checking the length inside. The old version is preserved for now as the rtl* drivers use it and don't have a correct skb.

| | | | | | | | | | | | | | | | | | | | | | | | There's not a single rate control algorithm actually in a separate module where the module refcount would be required. Similarly, there's no specific rate control module. Therefore, all the module handling code in rate control is really just dead code, so remove it.
