In function wma_extscan_change_results_event_handler(), numResults
in dest_chglist is assigning as total_entries in the event, but the
memory allocated to dest_chglist is based on the numap variable,
which may cause out of buffer read in extscan indication callback
function wlan_hdd_cfg80211_extscan_signif_wifi_change_results_ind().
Also tSirWifiSignificantChange array parsing in both the functions
is not efficient which may lead to accessing unallocated memory.
To address out of buffer read, assign numap to numResults in
dest_chglist and to address accessing of unallocated memory,
parse tSirWifiSignificantChange array with efficient logic.

User can override the Listen Interval value set during association
by using wifi config set vendor command. Since there is no limit
check in host, a very high value causes an assert in the Firmware.
Add an upper limit check on the user Listen Interval value.

During the review of "qcacld-3.0: lim: Replace tSirRetStatus with
QDF_STATUS" it was observed that the documentation for function
pe_process_messages() referenced an incorrect return type and return
value. While addressing this issue it was further observed that
pe_process_messages() was only being called from within lim_api.c by
pe_mc_process_handler(). Since these are both trivial functions,
consolidate them into one function.

A recent set of changes replaced all tSirRetStatus definitions with

Currently lim_post_msg_api() and lim_post_msg_high_priority() are
defined to return a uint32_t status. This is an artifact of many
generations of driver changes. These functions now return QDF_STATUS,
so update the signatures as well as all callers to properly expect
this return type. In addition remove the legacy wrapper function
pe_post_msg_api() since it is unused.

rx_thread can sustain the TCP DL KPIs with silver core.
So let system decide scheduling of rx_thread for TCP.
Move rx_thread to perf cluster only for UDP traffic exceeding
the threshold. This is achieved by having monitoring non
rx_offload traffic. This takes care of platform(such as ROME)
which doesnot support rx_offload and also cases when we don't
support rx_offload(SAP, concurrency etc..)
This rx_thread affinity can be overridden by INI configured
rx_thread CPU mask.

Current NAPI IRQ affinity logic doesnot have way to specify

If ini gWlanMccToSccSwitchMode is selected to
QDF_MCC_TO_SCC_WITH_PREFERRED_BAND(6) then following will be the
behaviour of STA+SAP concurrency.
1. If second interface(SAP/STA) comes in same band as
first interface(STA/SAP) respectively then force SCC
irrespective of channel.
2. If second interface(SAP/STA) comes in other band as
first interface(STA/SAP) then dont force SCC allow
interband MCC or DBS based on DBS capability.
Allow interband MCC but not intraband MCC.

If wmi_ready is not set, we can infer that WMI_READY_EVENTID has not
been fully processed yet. Completion of WMI_READY_EVENTID is necessary
for any follow-on messages to be processed properly, since it builds
infrastructure on host. Therefore, serialize the follow-on message with
WMI_READY_EVENT if wmi_ready is not set yet.

While processing the WMA_ROAM_OFFLOAD_SYNCH_IND event, The
driver takes nearly 150 to 200 msec time to just write fatal,
error and info messages to the kmsg log buffer. Also to get
tx power supplicant runs another thread while roaming. These
cause more latency(300ms) to send WMA_ROAM_OFFLOAD_SYNCH_CNF
message to fw. To decrease roam latency, the driver should
write the only necessary error message to kmsg buffer.
The fix is to change irrelevant fatal, error and info message
type to debug add a check in __wlan_hdd_cfg80211_get_txpower
to reject the request to get Tx power while roaming in progress
otherwise driver will process this and will increase the roaming
latency.
