Move most of CHANWIDTH_* definitions from ieee80211_defs.h to defs.h as
the definitions are getting used mostly for internal purpose only. Also
change prefix of the definitions to CONF_OPER_CHWIDTH_* and update in
all the files accordingly.
Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

This information element is similar to the CSA one. It contains a

the new color happens.
Just note the current implementation is based on CCA counter attributes
that only take Beacon and Probe Response framesinto account.
(Re)Association Response frames do not currently have kernel APIs to
decrement the CCA counter since mediatek mcu firmware does not support
it yet and it will be added in future firmware release.

This is a workaround for mac80211 behavior of retransmitting the
Association Request frames multiple times if the link layer retries
(i.e., seq# remains same) fail. The mac80211 initiated retransmission
will use a different seq# and as such, will go through duplicate

be two different DH shared secrets and the STA would likely select the

IEEE Std 802.11-2020 mandates H2E to be used whenever an SAE password
identifier is used. While this was already covered in the

argument for specifying the password identifier since that was used in

no more need for this argument anymore. Simplify the older non-H2E case
to not pass through a pointer to the (not really used) password

Reordering of code in handle_auth_cb() when adding support for full
station state messaged up frame length checks. The length was originally
tested before looking at the payload of the frame and that is obviously
the correct location for that check. The location after those full state
state changes was after having read six octets of the payload which did
not help at all since there was no addition accesses to the payload
after that check.
Move the payload length check to appropriate place to get this extra
level of protection behaving in the expected manner. Since this is a TX
status callback handler, the frame payload is from a locally generated
Authentication frame and as such, it will be long enough to include
these fields in production use cases. Anyway, better keep this check in
working condition.
