This is needed to allow the driver to know on which operating channel
(as specified by the link that is affiliated with AP MLD for the current
association) is used for transmitting TDLS Discovery Response. This
commit adds the link_id parameter to various functions, but does not
implement the driver interface change itself.

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
the first bss. The first report would otherwise clear hapd->cca_color and
subsequent reports would cause the iface bss color to be set to 0.
In order to avoid any issues with cancellations, only overwrite the color
based on hapd->cca_color if it was actually set.

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.

Add new nested netlink attribute, NL80211_ATTR_EMA_RNR_ELEMS, to send
the reduced neighbor report (RNR) elements to the driver when EMA is
enabled. This attribute includes the count of RNR elements and data at
each index. While generating EMA beacons, the driver will include RNR
group at a given index along with MBSSID group. The last element, if
present, has RNR data common for all EMA beacons such as neighbor APs.

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.
