Future patches will move the drivers for RTL8192EE and RTL8821AE from staging to the regular wireless tree. Here, the necessary features are added to the PCI driver. Other files are touched due to changes in the various data structs. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

When the rtlwifi family of drivers was converted to use a workqueue when entering or leaving power save mode (commits a269913c, a5ffbe0a, 41affd52, b9116b9a, and 6539306b), the code began scheduling work from the callback routine of a different workqueue with a resulting increase in overhead.

Clearing IEEE80211_TX_CTL_PS_RESPONSE in a frame that is not in the current context doesn't seem right. Instead make sure that we don't add such frames to the UAPSD queue by using a local variable.

There is no reason why frames marked with IEEE80211_TX_CTL_TX_OFFCHAN have to be sent using the UAPSD queue. Since mac80211 makes sure that RoC is done before pushing an offchannel frame to the driver, we can use the normal TX queues for transmission.

Since we use IEEE80211_HW_QUEUE_CONTROL now, the CAB/Offchannel queues are registered as the last two queues. There is no need to check and reassign the queues in the TX start()/done() routines. CAB frames will not reach the tx() callback since we set IEEE80211_HW_HOST_BROADCAST_PS_BUFFERING and pull the buffered frames during beacon transmission. We also don't have a special HW queue for handling off-channel frames. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This patch makes the driver to report signal strength information to mac80211 for rtl8187se boards. It differs from my previous RFT patch: http://marc.info/?l=linux-wireless&m=140155388332534&w=2 because: - I have now a working rtl8187se card, so I could serve my RFT by myself. :) - CCK measurement code has changed a bit, but it does basically the same things. - OFDM measurement method is changed because the older method reported incorrect measures, at least for signals stronger than -40dBm). CCK measurement seems quite good. OFDM seems less accurate, but this is the same as the "reference" staging driver dose. I wanted not to change things just to make measures of _one_ (my) card a bit more close to what _I_ (in my setup) expected.. IMHO results are still good enough to justify reporting signal in dBm rather than in "unspecified" units, so this is what this patch actually does. Results of my tests with a working rtl8187se card connected with coaxes and various RF attenuators to my AP are: Input (approx) | CCK meas | OFDM meas -------------------------------------- -30dBm | -32dBm | -31dBm -40dBm | -40dBm | -41dBm -50dBm | -50dBm | -55dBm -60dBm | -59dBm | -63dBm -70dBm | -69dBm | -73dBm -80dBm | -79dBm | -83dBm Also some real-field tests has been done (no coax, packets in the air) for the CCK measure method, and they resulted in reasonable values.

When multiple channel contexts are enabled, a p2p interface that is assigned to a context will have an address that is different from the device mac address, which is used by wpa_s as the p2p device ID. Certain frames like provision requests use the device address and these get dropped since ath9k_calculate_summary_state() iterates over only the active interfaces in a context and the device address is not used. Fix this by adding the device mac address to the bssid mask. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Using the BSS information stored in mac80211 directly is racy in certain conditions. For example, in a MCC setup, if the scheduler is switching channels when a local deauth is issued, calculation of the opmode/bssid etc. is incorrect. To avoid this, store the bss params in the driver and use it. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

AHB bus support was added in v2.6.38, through commit a0b907ee ("ath5k: Add AHB bus support."). That code can only be build if the Kconfig symbol ATHEROS_AR231X is set. But that symbol has never been added to the tree. So AHB bus support has always been dead code. Let's remove all code that depends on ATHEROS_AR231X. If that symbol ever gets added to the tree the AHB bus support can be re-added too. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: John W. Linville <linville@tuxdriver.com>

It is expected that new parameter combinations will have the retransmission effort value different between some entries (mainly because of the new S4 configuration added by HFP 1.7), so it makes sense to move it into the table instead of having it hard coded based on the selected SCO_AIRMODE_*.

The 6lowpan ipv6 header compression was causing problems for other interfaces that expected a ipv6 header to still be in place, as we were replacing the ipv6 header with a compressed version. This happened if you sent a packet to a multicast address as the packet would be output on 802.15.4, ethernet, and also be sent to the loopback interface. The skb data was shared between these interfaces so all interfaces ended up with a compressed ipv6 header. The solution is to ensure that before we do any header compression we are not sharing the skb or skb data with any other interface. If we are then we must take a copy of the skb and skb data before modifying the ipv6 header. The only place we can copy the skb is inside the xmit function so we don't leave dangling references to skb. This patch moves all the header compression to inside the xmit function. Very little code has been changed it has mostly been moved from lowpan_header_create to lowpan_xmit. At the top of the xmit function we now check if the skb is shared and if so copy it. In lowpan_header_create all we do now is store the source and destination addresses for use later when we compress the header.

The core specification defines valid values for the HCI_Reject_Synchronous_Connection_Request command to be 0x0D-0x0F. So far the code has been using HCI_ERROR_REMOTE_USER_TERM (0x13) which is not a valid value and is therefore being rejected by some controllers: > HCI Event: Connect Request (0x04) plen 10 bdaddr 40:6F:2A:6A:E5:E0 class 0x000000 type eSCO < HCI Command: Reject Synchronous Connection (0x01|0x002a) plen 7 bdaddr 40:6F:2A:6A:E5:E0 reason 0x13 Reason: Remote User Terminated Connection > HCI Event: Command Status (0x0f) plen 4 Reject Synchronous Connection (0x01|0x002a) status 0x12 ncmd 1 Error: Invalid HCI Command Parameters This patch introduces a new define for a value from the valid range (0x0d == Connection Rejected Due To Limited Resources) and uses it instead for rejecting incoming connections.

In NFC Forum NCI specification, some RF Protocol values are reserved for proprietary use (from 0x80 to 0xfe). Some CLF vendor may need to use one value within this range for specific technology. Furthermore, some CLF may not becompliant with NFC Froum NCI specification 2.0 and therefore will not support RF Protocol value 0x06 for PROTOCOL_T5T as mention in a draft specification and in a recent push. Adding get_rf_protocol handle to the nci_ops structure will help to set the correct technology to target.
