We attach the "counter" to the tcpcbs. Thus don't free the
TCP Fastopen zone before the tcpcbs are gone, as otherwise
the zone won't be empty.
With that it should be safe to destroy the "tfo" zone without
leaking the memory.

While there is no dependency interaction, stopping the timer before
freeing the rest of the resources seems more natural and avoids it
being scheduled an extra time when it is no longer needed.

* Don't use arbitrary frames for the average RX RSSI - only frames
from the current BSSID
* Don't log / do the syncbeacon logic for another BSSID and definitely
don't do the syncbeacon call if we miss beacons outside of STA mode.
* Don't do the IBSS merge bits if the current node plainly won't ever
match our current BSS (ie, the IBSS doesn't have to match, but all
the same bits that we check in ieee80211_ibss_merge() have to match.)
Tested:
* ath(4), AR9380, IBSS mode, surrounded by a lot of IBSS 11ac networks.
Sponsored by: Eva Automation, Inc.
The ath(4) driver now sees beacons and management frames for different
BSSIDs in IBSS mode, which is a problem when you're in a very busy
IBSS environment.
So, expose this function so drivers can use it to check if the current
RX node is actually for a BSS we need to pay attention to or not.

This prevents nodes being created for peers on BSSes that are not our own.
(Ie, same channel, IBSS, but different BSS.)
The "IBSS merge" thing was fixed by me enabling "see all beacons" in
the ath(4) driver a few months ago. Trouble is, we now need the filtering
again.
Tested:
* ath(4), IBSS, on a very busy IBSS channel with lots (> 15) IBSS networks.

USB on both MT7621 and MT7688 seems to work much better without doing
slew rate calibration.
These are the only two SoCs, apart from MT7628, which actually make
use of the slew rate calibration routines implemented in the mtk_usb_phy
driver. Since MT7628 is actually a superset of MT7688 things should be
the same for it as well.
We do not remove the code, we simply define it out.

This is rather ugly, because the RIPE and APNIC whois servers do
not provide referrals for address blocks that they do not manage.
However ARIN is usually the right place or knows the right place
so we try there.
The particular instance which clued me in to this bug is U.Mich.
141.211.0.0/16 for which the referral chain should be IANA ->
RIPE -> ARIN. RIPE's RDAP does provide useful redirects (for
example try `curl -I http://rdap.db.ripe.net/ip/141.211.0.0)
so maybe their whois server can be improved.
AfriNIC's whois server gives more direct referrals, but they are
designed to be human-readable. Ugly, but we can manage.
The issue of referrals between RIRs is likely to become more important
in the future whith the increasing number of cross-region IP address
block transfers increases.
The previous values caused the callout thread stall for 100ms each 2s
if no link is present. Dtrace analysis showed that it has significant
impact on overall interrupt performance.
Decrease these values by a factor of 100.

Currently we don't keep zoneid in in6_ifaddr structure, because there
is still some code, that doesn't properly initialize sin6_scope_id,
but some functions use sa_equal() for addresses comparison. sa_equal()
compares full sockaddr_in6 structures and such comparison will fail.
For now use zero zoneid in in6ifa_ifwithaddr(). It is safe, because
used address is in embedded form. In future we will use zoneid, so mark it
with XXX comment.

aq64_minfree is unsigned so comparing to find out if it is less

as we don't want to spend time if any of the others triggers first.
hile it would be tempting to just remove it, it may be important to
keep it for portability with platforms where may be signed(?) or

This flag indicates that the user wishes to use the GELIBOOT feature to boot from a fully encrypted root file system.
Currently, GELIBOOT does not support key files, and in the future when it does, they will be loaded differently.
Due to the design of GELI, and the desire for secrecy, the GELI metadata does not know if key files are used or not, it just adds the key material (if any) to the HMAC before the optional passphrase, so there is no way to tell if a GELI partition requires key files or not.
Since the GELIBOOT code in boot2 and the loader does not support keys, they will now only attempt to attach if this flag is set. This will stop GELIBOOT from prompting for passwords to GELIs that it cannot decrypt, disrupting the boot process
