Currently legacy thermal throttle level can support to
THROTTLE_LEVEL_3 at the most. Per new thermal mitigation
requirement, it's needed to add extra implementation
for TX off processing and target shutdown. So extend
throttle level to THROTTLE_LEVEL_5.

Currently, data stall detection is without control over
individual data stall events.
INI variable, gEnableDataStallDetection is converted from
boolean to unsigned int which provides control over events
across FW and host with each bit corresponding to different
data stall events.
Bit 0: Enable all data stall events if set.
Bit 1-30: mapped to data stall events. Used when Bit 0 is 0
Bit 31: Enable aggressive timeout for WLM Mode.

Due to DP flow control network queues are stuck in
paused state and not getting reset even after new connection.
This is causing DHCP packets to be dropped and resulting
immediate disconnection after every connection.
Fix this by properly pausing and unpausing the AC flow control
based network subqueues during disconnection/connection events.

qcacld-2.0 to qcacmn propagation
This change adds support for driver supported TCP
delayed ack to increase TCP RX performance in
third-party platform which don't support kernel
TCP delayed ack feature.
TCP delayed ack is dependent on count and timer
values. Whatever is achieved first will trigger
sending TCP ack.
This feature can be controlled through ini values.
gDriverDelAckTimerValue - timer value in ms
gDriverDelAckPktCount - delayed ack count
gDriverDelAckEnable - enable/disable feature

Add stop_th and start_th for QCA_LL_TX_FLOW_CONTROL_V2 disabled
platform, which is pdev based tx_desc pool. Change pdev tx_desc pool
size from 1056 to 900, default stop_th is 15% start_th is 25%, this
setting is exactly same as QCA_LL_TX_FLOW_CONTROL_V2. Pause netif tx
queues for all vdevs when stop_th reached instead of dropping frames.
Reduce pdev pool size could significantly reduce firmware wmm drop. Both
of host and firmware frame dropps lead to bad TCP throughput.

When the status is FLOW_POOL_ACTIVE_PAUSED, all queues are expected to
be paused. Still some on the fly packet can make it to the driver. In
such a case, the function dp_tx_desc_alloc takes a default action of
WLAN_WAKE_NON_PRIORITY_QUEUE. This is incorrect, since it will wake all
non priority queues, when they should be paused.
Make default action as WLAN_NETIF_ACTION_TYPE_NONE. If this is the
action to be taken, donot call the pause_cb from dp_tx_desc_alloc.
Rate limit log levels in case dp_tx_desc_alloc fails.
