RX MCS set defines which MCSs are supported for RX, bits 0-31 are for equal
modulation of the streams, bits 33-76 are for unequal case. Current code checks
txstreams variable instead of rxstreams to set bits from 53 to 76 for 4 spatial
streams case.
The modulations are defined in tables 19-38 and 19-41 of the IEEE Std
802.11-2020.

Current code checks whether or not txstreams are equal to rxstreams and if it
isn't - sets needed bits in "Transmit MCS Set". But if they are equal it sets
whole set to zero, which contradicts the standard, if tx and rx streams are
equal 'Tx MCS Set Defined' (table 9-186, IEEE Std 802.11-2020) must be set to
one.

* Add link-state change notifications by subscribing to ifnet_link_event.
In the Linux netlink model, link state is reported in 2 places: first is
the IFLA_OPERSTATE, which stores state per RFC2863.
The second is an IFF_LOWER_UP interface flag. As many applications rely
on the latter, reserve 1 bit from if_flags, named as IFF_NETLINK_1.
This flag is mapped to IFF_LOWER_UP in the netlink headers. This is done
to avoid making applications think this flag is actually
supported / presented in non-netlink outputs.
* Add flag change notifications, by hooking into rt_ifmsg().
In the netlink model, notification should include the bitmask for the
change flags. Update rt_ifmsg() to include such bitmask.

Remove the KPI/KBI changes from ieee80211_node.h and always use the
macros to pass in __func__ and __LINE__ to the functions.
The actual implementations are prefixed by "_" rather than suffixed
by "_debug" as they no longer are "debug"-specific.
Some of the select functions were not actually using the passed in
func, line options; however they are calling other functions which
use them. Directly call the internal implementation in those cases
passing the arguments on.
Use a file-local __debrefcnt_used define to mark the arguments __unused
in cases when we compile without IEEE80211_DEBUG_REFCNT and hope the
toolchain is intelligent enough to not pass them at all in those cases.
Also _ieee80211_free_node() now has a conflict so make the previous

This took an embarrasingly long time to find.
The state changes for a radio with a STA /and/ AP VAP gets a bit messy.
The AP maps are marked as waiting, waiting for the STA AP to find a
channel to use before the AP VAPs become active.
However, the code path that clears the OACTIVE flag on a VAP only runs
during a successful run of ieee80211_newstate_cb().
So here is how it goes:
* the STA VAP goes down and needs to scan;
* the AP vap goes RUN->INIT; but it doesn't YET call ieee80211_newstate_cb();
* meanwhile - a send on the AP VAP causes the VAP to set the OACTIVE flag here;
* then the STA VAP finishes scan and goes to RUN;
* which will call wakeupwaiting() as part of the STA VAP transition to RUN;
* .. then the AP VAP goes INIT->RUN directly via a call to hostap_newstate
in wakeupwaiting rather than it being through the deferred path;
* /then/ the ieee80211_newstate_cb() is called, but it sees the state go
RUN->RUN;
* .. which results in the OACTIVE flag never being cleared.
This clears the OACTIVE flag when a VAP transitions RUN->RUN; the
driver layer or net80211 layer can set it if required in a subsequent
transmit.
