Packets sent/received at fixed rate were also considered to
update the client rates as displayed in wlanconfig command output.
An idle client transmits NULL packets at basic rate and hence
rx rate shows up the basic rate when an idle client is connected.
Consider only data packets to update rates. Do not consider
NULL packets for rate update.

wlan_vdev_get_bsspeer() return bss peer without taking the ref count
of the peer and thus if peer is deleted after wlan_vdev_get_bsspeer()
returns a valid peer, the caller will have stale entry of the peer.
Stale entry of peer can lead to Assert.
Use wlan_objmgr_vdev_try_get_bsspeer API for stats to get the BSS
peer which increment the refcount if peer is valid. With this the
peer won't be deleted till the caller release the ref count of the
peer.

Currently cached rx buffer frames are forwarded to stack
at the time of successful association completion. If the
association with the AP is unsuccessful frames are not
flushed and this leads to memory leak. To fix this clear

atomic variable is not decremented before return. Fix
this by removing the code to check list empty as the

basically tried reading peer_id from peer structure
to avoid 1 cache-line miss per pkt and access mac address
from frame data for WDS only if WDS condition is valid.
The other optimization is to avoid accessing queue_mapping
field of skb for skb received which is at 140 offset
This again helps to avoid i cache miss.
Another place is to do a memcpy only when we intend to
add an ast entry.

since there is pending outstanding TX data on this vdev, but later
FW/HW still indicate the TX completion to host and which likely
these TX completion get delayed, conflict happened due to same TX
Desc accessing.
To fix it:
(1) Only reset TX desc Vdev to NULL in dp_tx_vdev_detach().
(2) Do more enhancement in dp_tx_comp_handler() to avoid
invalid Vdev accessing.
(3) Do TX desc flush in dp_tx_pdev_detach().

In practice, some APs have interop issues with the DUT. This sub command
is used to transfer the AP info between the driver and user space. This
works both as a command and event. As a command, it configures the
stored list of APs from user space to firmware; as an event, it
indicates the AP info detected by the firmware to user space for
persistent storage. The attributes defined in enum
qca_vendor_attr_interop_issues_ap are used to deliver the parameters.

The function target_if_direct_buf_rx_rsp_event_handler() handles
the WMI_PDEV_DMA_RING_BUF_RELEASE_EVENTID event from target.
This function calls extract_dbr_buf_release_fixed_tlv() to copy
the module id, pdev id number of buffer release entry and number
of meta data release entries. The value of module id is used to
index the array dbr_mod_param to get the value of mod_param.
So if the module id value greater than dbr_pdev_obj->num_modules
could result in possible OOB.
Validate mod_id received in the fixed param of the event
WMI_PDEV_DMA_RING_BUF_RELEASE_EVENTID against
dbr_pdev_obj->num_modules.
