While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
from the passed bitrate, there is a chance of out of bound array access
when wrong bitrate is passed. This is fixed by comparing the bitrates
within the correct size of the ath10k_rates array.
Fixes commit f279294e9e ("ath10k: add support for configuring management
packet rate"). Also correction made to some indents used in the above commit.

Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.
This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

This patch helps to get the power save state change of each peer
connected to the AP. With WMI_10_4_PEER_STA_PS_STATECHG_EVENTID
event, ps state of each peer is reported to user space via
debugfs.
Use the below command to get the ps state of each sta:
cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/
XX:XX:XX:XX:XX:XX/peer_ps_state
If STA is in power save state, we get the peer_ps_state value as 1.
if STA is not in power save state, we get the peer_ps_state value as 0.
If ps_state event is disabled, we get the peer_ps_state value as 2.
We can enable/disable the ps_state events using the debugfs flag
"ps_state_enable"
echo Y > /sys/kernel/debug/ieee80211/phyX/ath10k/ps_state_enable
Y = 1 to enable and Y = 0 to disable

By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.
This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

Since commit 9d5804662c ("ath10k: retrieve MAC address from system

firmware. Along with this, we should admit that it's possible for system
firmware to be screwed up as well, omitting the MAC address there.
Provide a fallback, such that we choose a randomly-generated MAC
address, with the local assignment bit set.
This is not a preferred mode of operation and really should only serve
the purpose of keeping the system chugging along while someone figures
out what's wrong with the system. Grepping through other wireless
drivers shows very similar fallback logic though, so why not?
