41baf0159a nl80211: Fix uses_6ghz flag
Presence of any 6ghz channels indicates nl80211 driver 6 GHz support,
not non-DISABLED channels. This increases the timeout for scan
completion for cases where 6 GHz might get scanned even if all the
channel there are currently DISABLED.

bffd2b3994 nl80211: Skip interface down/up when setting MAC address
A driver may not support setting MAC address when interface is UP, so
wpa_supplicant used to always sets the interface down for MAC address
change.

Try to change the address first without setting the interface down and
then fall back to DOWN/set addr/UP if the first attempt failed. This can
reduce the interface setup time for time-critical use cases.

0a6842d503 nl80211: Fix beacon rate configuration for legacy rates 36, 48, 54 Mbps
Typecasting takes precedence over division here, so the legacy rates
larger than 255 * 100 kbps (i.e., 36, 48, 54 Mbps) ended up getting
truncated to invalid values.

Fix this by typecasting the value after the division.

Pass bss->ctx instead of drv->ctx in order to avoid multiple reports for

9b233e9f0a nl80211: Always return NL_SKIP from survey dump handler
Previously, NL_STOP was returned from the survey dump handler if the
maximum number of frequencies was reached for storing survey
information, but this is causing wpa_supplicant context getting stuck if
the current SKB returned by the kernel itself ends with NLMSG_DONE type
message. This is due to libnl immediately stopping processing the
current SKB upon receiving NL_STOP and not being able to process
NLMSG_DONE type message, and due to this wpa_supplicant's
finish_handler() not getting called. Fix this by returning NL_SKIP
instead while still ignoring all possible additional frequencies.

5d06acefdd RNR: Add elements by default for EMA AP
As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of
a nontransmitted BSSID profile, an EMA AP that transmits a Beacon
frame carrying a partial list of nontransmitted BSSID profiles
should include in the frame a Reduced Neighbor Report element
carrying information for at least the nontransmitted BSSIDs that
are not present in the Multiple BSSID element carried in that frame.

Add this support by splitting the reduced neighbor report (RNR) in as
many elements as the number of multiple BSSID elements. Each RNR element
excludes the non-transmitting profiles already included in the MBSSID
element at the same index. If present, the last additional group will
have the data common for all EMA beacons such as neighbor AP information
gathered through neighbor reports.

The hwsim test case he_ap_ema demonstrates this support.
