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. Also as RealTek's testing results, RTL8188EE and RTL8723BE work well with both MSI mode and pin-based mode fallback. Signed-off-by:

It has been observed that system hangs during suspend, if host sleep activation fails due to a missing interrupt from firmware. Use timeout variant, so that the thread will be woken up when timer expires. Signed-off-by:

When a thread is interrupted by signal, all wait_event_interruptible calls after queueing commands return an error. Numbers of commands in pending queue are increased in this case. Sometimes all commands nodes in pool are filled. We will cancel pending commands when signal is received. Signed-off-by:

When scan request is received, scan commands are prepared and queued into scan pending queue. There is a corner case when command nodes are full. So we stop queueing further scan commands and return an error. This patch makes sure that currently queued commands in scan pending queue are also freed in this case. Signed-off-by:

rtl8180 has one register for analog converters setting ,rtl8185 has two and rtl8187se has three. Setting those registers require more than a simple write, and for one of them a function is already provided. This patch introduces functions for the other two. rtl8187se will use them. rtl8185 doesen't yet, but should Signed-off-by:

Currently RX status descriptor and RX command descriptor are represented using the same struct type. This patch splits this by introducing different types for rx status and command descriptor. Doing this make it possible to handle rtl8187se RX descriptors easier. This patch do also this by adding specific cases where needed. Signed-off-by:

When next scan command is delayed due to Tx traffic and meanwhile synchronous command is received followed by a signal, we cance all pending commands. NULL pointer dereference is seen in this case while queueing next command in scan delay timer. This patch adds a check to fix this issue. Signed-off-by:

The struct cfg80211_connect_params indicate whether the connection should use management frame protection (mfp). If required set the MFP_CAPABLE flag in the firmware command. This is supported from user-space by wpa_supplicant since v2.1. Reviewed-by:

On currently supported HW there are four TX queues (three for normal packets and one for beacons). The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by:

Hw DMA registers are written in rtl8180_init_hw function. They are also written again just after calling rtl8180_init_hw. There is no point in doing this twice. Remove those redundant register writes from rtl8180_start. Signed-off-by:

We should let user space request the peer address also in the pending connect states, i.e. BT_CONNECT and BT_CONNECT2. There is existing user space code that tries to do this and will fail without extending the set of allowed states for the peer address information. This patch adds the two states to the allowed ones in the L2CAP and RFCOMM sock_getname functions, thereby preventing ENOTCONN from being returned. Reported-by:

The smp variable in smp_conn_security is not used anywhere before the smp = smp_chan_create() call in the smp_conn_security function so it makes no sense to assign any other value to it before that. Signed-off-by:

The smp pointer might not be initialized for jumps to the "done" label in the smp_conn_security function. Furthermore doing the set_bit after done might "overwrite" a previous value of the flag in case pairing was already in progress. This patch moves the call to set_bit before the label so that it is only done for a newly created smp context (as returned by smp_chan_create). Signed-off-by:

Due to several devices being unable to handle this procedure reliably (resulting in forced disconnections before pairing completes) it's better to remove it altogether. Signed-off-by:
