Indicates whether the STA is capable of interpreting the Extended NSS BW
Support subfield of the VHT Capabilities Information field.

Some APs, such as Xiaomi AX6000, would check this one for BW settings.
mt76 driver can get max BW capability only if the this field is confgured

Increase akm_suites array size in struct cfg80211_crypto_settings to 10
and advertise the capability to userspace. This allows userspace to send
more than two AKMs to driver in netlink commands such as
NL80211_CMD_CONNECT.

This capability is needed for implementing WPA3-Personal transition mode
correctly with any driver that handles roaming internally. Currently,
the possible AKMs for multi-AKM connect can include PSK, PSK-SHA-256,
SAE, FT-PSK and FT-SAE. Since the count is already 5, increasing
the akm_suites array size to 10 should be reasonable for future
usecases.

The current check only worked for AP mode, but we can do
radar detection in mesh as well (for example). We could
try to check this using wdev_chandef(), but we also don't
really care since the chandef is passed in and we have no
need to use it anymore (since we added the argument in
commit d2859df5 ("cfg80211/mac80211: DFS setup chandef

In many cases we might get here from driver code that's
not really set up to care about the locking, and for the
non-MLO cases we really don't care so much about it. So
relax the checking here for now, perhaps we should even
remove it completely since we might not really care if
we point to an invalid link's chandef and can require
the caller to check the link validity first.
