wiphy parameter - wiphy_radio_cfg, as an array. Add a new attribute -
NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD in nested parameter -
NL80211_ATTR_WIPHY_RADIOS. When a request for getting RTS threshold
for a particular radio is received, parse the radio id and get the
required data. Add this data to the newly added nested attribute
NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD. Add support to report this
data to userspace.
wifi: cfg80211: Add Support to Set RTS Threshold for each Radio
Currently, setting RTS threshold is based on per-phy basis, i.e., all the

from userspace. But each radio in a multi-radio wiphy can have different
RTS threshold requirements.
To extend support to set RTS threshold for each radio, get the radio for
which RTS threshold needs to be changed from the user. Use the attribute
in NL - NL80211_ATTR_WIPHY_RADIO_INDEX, to identify the radio of interest.
Create a new structure - wiphy_radio_cfg and add rts_threshold in it as a
u32 value to store RTS threshold of each radio in a wiphy and allocate

NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX

Statistics such as packets, bytes, signal, rates, etc are useful to

However, MLO statistics for rates and signal can not be accumulated since

The signal could be the best of all links-
e.g. if Link 1 has a signal strength of -70 dBm and Link 2 has -65 dBm,
the signal for MLO will be -65 dBm.
The rate could be determined based on the most recently updated link-
e.g. if link 1 has a rate of 300 Mbps and link 2 has a rate of 450 Mbps,
the MLO rate can be calculated based on the inactivity of each link.
If the inactive time for link 1 is 20 seconds and for link 2 is 10 seconds,
the MLO rate will be the most recently updated rate, which is link 2's
rate of 450 Mbps.

wifi: ath12k: Fix double budget decrement while reaping monitor ring
Currently, the budget for monitor ring is reduced during each ring entry
reaping and again when the end reason is HAL_MON_END_OF_PPDU, leading to
inefficient budget use. The below mentioned commit intended to decrement
the budget only for HAL_MON_END_OF_PPDU but did not remove the other
decrement. Fix this by eliminating the budget decrement for each ring entry
reaping, ensuring the driver always reaps one full PPDU worth of entries
from the monitor destination ring.

The commit 89ac53e96217 ("wifi: ath12k: Enable REO queue lookup table
feature on QCN9274") originally intended to enable the reoq_lut_support
hardware parameter flag for both QCN9274 hw1.0 and hw2.0. However,
it enabled it only for QCN9274 hw1.0.
Hence, enable REO queue lookup table feature on QCN9274 hw2.0.
