Avinash Patil 5a009adf32 mwifiex: add 11n Block Ack support for uAP
This patch adds support for handling BA request and BA setup
events for AP interface.

RA list is marked as either 11n enabled or disabled from station's
capabilities in association request. BA setup is initiated only
after some specific number of packets for particular RA list are
transmitted.

Avinash Patil 838e4f4492 mwifiex: improve uAP RX handling
1. Separate file for uAP RX handling.
2. If received packet is broadcast/multicast, send it to kernel
   as well as requeue it back to uAP TX queue.
3. If received packet is for associated STA (intra-BSS), requeue
   it back to uAP TX queue.
4. In all other cases (packets for AP or inter-BSS packets),
   pass packet to kernel to handle it accordingly.

Amitkumar Karwar bdd37bed61 mwifiex: improve scan delay logic during Tx traffic
Earlier scan command was postponed by 20msec multiple times to give
preference to Tx traffic until we find empty wmm queue.

There is a corner case in which wmm queue becomes empty immediately
after processing the packet(before 20msec) and there may be next
packet coming after some time. In this case we should not resume scan
operation.

We will use new flag to check Tx traffic and resume scan operation
only if there is no traffic for 200msec.

Larry Finger 95a96e0896 p54pci: convert driver to use asynchronous firmware loading
Drivers that load firmware from their probe routine have problems with the
latest versions of udev as they get timeouts while waiting for user
space to start. The problem is fixed by using request_firmware_nowait()
and delaying the start of mac80211 until the firmware is loaded.

To prevent the possibility of the driver being unloaded while the firmware
loading callback is still active, a completion queue entry is used.

Johannes Berg 50e2a30cf6 iwlwifi: disable greenfield transmissions as a workaround
There's a bug that causes the rate scaling to get stuck
when it has to use single-stream rates with a peer that
can do GF and SGI; the two are incompatible so we can't
use them together, but that causes the algorithm to not
work at all, it always rejects updates.

Disable greenfield for now to prevent that problem.

Szymon Janc a9ea3ed9b7 Bluetooth: Fix legacy pairing with some devices
Some devices e.g. some Android based phones don't do SDP search before
pairing and cancel legacy pairing when ACL is disconnected.

PIN Code Request event which changes ACL timeout to HCI_PAIRING_TIMEOUT
is only received after remote user entered PIN.

In that case no L2CAP is connected so default HCI_DISCONN_TIMEOUT
(2 seconds) is being used to timeout ACL connection. This results in
problems with legacy pairing as remote user has only few seconds to
enter PIN before ACL is disconnected.

Increase disconnect timeout for incomming connection to
HCI_PAIRING_TIMEOUT if SSP is disabled and no linkey exists.

To avoid keeping ACL alive for too long after SDP search set ACL
timeout back to HCI_DISCONN_TIMEOUT when L2CAP is connected.

This patch does a trivial code refactoring in hci_conn lookup in
hci_le_conn_complete_evt. It performs the hci_conn lookup at the
begining of the function since it is used by both flows (error
and success).

Andre Guedes 0c95ab78be Bluetooth: Find hci_conn by BT_CONNECT state
This patch changes hci_cs_le_create_conn to perform hci_conn lookup
by state instead of bdaddr.

Since we can have only one LE connection in BT_CONNECT state, we can
perform LE hci_conn lookup by state. This way, we don't rely on
hci_sent_cmd_data helper to find the hci_conn object.

Andre Guedes f00a06ac14 Bluetooth: Refactor hci_cs_le_create_conn
This patch does some code refactoring in hci_cs_le_create_conn
function. The hci_conn object is only needed in case of failure,
therefore hdev locking and hci_conn lookup were moved to
if-statement scope.

Also, the conn->state check was removed since we should always
close the connection if it fails.

Andre Guedes 847012c5e0 Bluetooth: Remove unneeded code
This patch removes some unneeded code from hci_cs_le_create_conn.

If the hci_conn is not found, it means this LE connection attempt
was triggered by a thrid-party tool (e.g. hcitool). We should not
create this new hci_conn in LE Create Connection command status
event since it is already properly handled in LE Connection
Complete event.
