7cac255632 HE: Fix Operation Parameters order
According to P802.11ax/D4.0 9.4.2.238 (HE Operation element) the BSS
Color Information field is located after the HE Operation Parameters
field. Fix the ordering of the bit masks/offsets for fields in these 3+1
octets used as a single 32-bit value. With these changes, Wireshark 3.2
is able to properly parse and display Beacon frames.

83f30fabe3 HE: Disable TXOP duration-based RTS if he_rts_threshold is not set
IEEE P802.11ax/D4.0 9.4.2.243 "HE Operation element" indicates that the
special value 1023 in the TXOP Duration RTS Threshold field is used to
indicate that TXOP duration-based RTS is disabled. Use that value as the
default instead of the previously used value 0 which would really mean
threshold of 0 usec. Furthermore, the previous implementation did not
allow values larger than 255 to be used for this field while the field
is actually 10 bits in size.

1b90aae929 nl80211: Remove QCA vendor specific HE capability handling
The QCA_NL80211_VENDOR_SUBCMD_GET_HE_CAPABILITIES attributes are not
up-to-date with the latest P802.11ax/D4.0 capabilities and would need to
be updated or replaced. Since the variables from this functionality were
not used for anything in practice, it is easier to simply remove this
functionality completely to avoid issues with upcoming updates to use
upstream nl80211 information to determine HE capabilities.

This is practically reverting the commit ca1ab9db2a ("hostapd: Get
vendor HE capabilities").

A DPP TCP connection can now be initiated directly from wpa_supplicant
with the new new tcp_port and tcp_addr parameters to the DPP_AUTH_INIT
control interface command. This initiates DPP Authentication exchange
over TCP with the specified Controller instead of using DPP Public
Action frames over WLAN.

The new hostapd configuration parameter dpp_controller can now be used

pkhash=<hexdump>. This adds a new Controller into the configuration
(i.e., more than one can be configured) and all incoming DPP exchanges
that match the specified Controller public key hash are relayed to the
particular Controller.

a40bd06e9b FILS: Fix PTK rekeying
The PMK and PMKID information from FILS ERP and FILS PMKSA caching needs
to be stored within struct wpa_state_machine for PTK to work. Without
this, PTK derivation would fail and attempt to go through rekeying would
result in disconnection. Furthermore, wpa_rekey_ptk() timer needs to be
started at the completion of FILS association since the place where it
was done for non-FILS cases at the end of 4-way handshake is not reached
when FILS authentication is used.
