f37a7dec3d Add vendor attributes for EPCS feature
Add vendor attribute QCA_WLAN_VENDOR_ATTR_CONFIG_EPCS_CAPABILITY
to set EPCS (Emergency Preparedness Communications Service)
feature capability.

Add vendor attribute QCA_WLAN_VENDOR_ATTR_CONFIG_EPCS_FUNCTION
to enable/disable EPCS priority access.

These are for testing purposes.

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.

3a995cb5a9 Determine current hw mode before channel switch
There are two hw modes (5 GHz and 6 GHz) with HOSTAPD_MODE_IEEE80211A
and the current hw mode may be wrong after one channel switch to 6 GHz.
This will cause hostapd_set_freq_params() to return -1 when saving
previous state and the second channel switch to fail. Fix this by adding
hostapd_determine_mode() before every channel switch.

In case the AP is an AP MLD, parse the Multi-Link element from the

If the AP is not an AP MLD or the parsing of the element fails, continue

For SAE, it is needed to skip various fixed fields in
the Authentication frame. Implement it for SAE with H2E.

TODO: This should be extended to other authentication algorithms which
are allowed for MLD connections and have fixed fields in the
Authentication frames, according to IEEE P802.11-REVme/D3.0, Table 9-69
(Presence of fields and elements in Authentications frames).
