Currently a set of IPA2TCL and WBM2IPA rings is used for
IPA TX data path. Issue is when wlan is configured as
SAP-SAP DBS mode, slow 2G traffic will consume much more
TX resources and thus 5G traffic will have starvation,
which leads to severe degradation of DBS KPI.
Therefore separate IPA2TCL (SW2TCL2) and WBM2IPA (WBM2SW4)
rings are added to support alternative IPA TX pipe for 2G
traffic.

Currently before suspending the device, we are draining
out the TX/RX SRNGs. The HP/TP updates which are done as
part of this will be posted writes(there won't be any link
levelccompletions for write transactions), there are chances
that we might end up updating HP/TP after the device enters
low power mode leading to system crashes.
In order to avoid this scenario, do a dummy read before
device is suspended; this will ensure all pendings writes are
flushed before read returns.

Currently dp_lro_hash_setup is being done in dp_vdev_attach_wifi3 when
pdev->vdev_count==1. However, this counter is not getting decremented and
may overflow on repeated VDEV attach/detach calls. This may result in
LRO keys being programmed again.
Use a PDEV flag to determine whether to configure LRO or not. Fix
pdev->vdev_count by decrementing it during VDEV detach.

Issue1: Driver RTPM state is ON/NONE, Kernel state is RESUMING.
cdp_runtime_resume is already complete,
hif_pm_runtime_get return -E_INPROGRESS,
dp_tx_hw_enqueue will set the flush event,
but cdp_runtime_resume is already done,
this flush event will be handled only on next pkt tx.
Issue2: Driver RTPM state: Resuming
hif_pm_runtime_get returns -EBUSY,
dp_tx_hw_enqueue is interrupted by any IRQ,
cdp_runtime_resume is completed,
dp_tx_hw_enqueue will set the flush event,
This flush event will be handled only on next pkt tx.
Fix:
Introduce a link_state_up atomic variable in hif to track the link state
change by pld_cb.
Set atomic variable link_state_up=1 in pmo_core_psoc_bus_runtime_resume
just after pld_cb. pld_cb brings the PCIe bus out of suspend state.
Set atomic variable link_state_up=0 in pmo_core_psoc_bus_runtime_suspend
just before pld_cb. pld_cb puts the PCIe bus into suspend state.
Introduce dp_runtime_get and dp_runtime_put.
dp_runtime_get get refcount with increment of an atomic variable.
dp_runtime_put return refcount with decrement of this atomic variable.
If hif_pm_runtime_get returns -EBUSY or -EINPROGRESS,
take the dp runtime refcount using dp_runtime_get,
check if the link state is up, write TX ring HP,
return the dp runtime refcount using dp_runtime_put.
cdp_runtime_suspend should reject the suspend, if dp_runtime_get is non
zero.
cdp_runtime_resume should wait until dp_runtime_get becomes zero or time
out, then flush pending tx for runtime suspend.

When runtime power management is enabled, until the system is fully
resumed, we do not post any message to CE, instead they will be queued
in HTC. Once the device is fully resumed, all HTT messages in the queues
will be downloaded to CE at once. In some corner cases, it is found that
too many FSE caches flush messages getting queued during the runtime
resume; once the device is fully resumed, all these would be downloaded
to the FW/HW at once causing unintended crashes.
Avoid posting FSE cache flush messages until the device is fully resumed
to fix the issue.
