Most options in kernel config files use "options<space><tab>OPTION".
This allows the option to be commented out without shifting columns.
A few options had two tabs, and some had spaces. Make them consistent.
They don't provide any value and are quite arbitrary.
Note arm64 GENERIC-MMCCAM was already excluded, just not the NODEBUG
variant.
The option is already build-tested with arm64 LINT kernel.

Netlink is a communication protocol defined in RFC 3549. It is async,
TLV-based protocol, providing 1-1 and 1-many communications between kernel
and userland. Netlink is currently used in Linux kernel to modify, read and
subscribe for nearly all networking states. Interface state, addresses, routes,
firewall, rules, fibs, etc, are controlled via Netlink.
Netlink support was added in D36002. It has got a number of improvements and
first customers since then:
* net/bird2 got netlink support, enabling route multipath in FreeBSD
* netlink-based devd notifications are being worked on ( D37574 ).
* linux(4) fully supports and depends on Netlink
Enabling Netlink in GENERIC targets two goals.
The first one is to provide stability for the third-party userland applications,
so they can rely on the fact that netlink always exists since 14.0 and potentially 13.2.
Loadable module makes life of the app delepers harder. For example, `net/bird2` can be
either build with netlink or rtsock support, but not both.
The second goal is to enable gradual conversion of the base userland tools
to use netlink(4) interfaces. Converting tools like netstat (D36529), route,
ifconfig one-by-one simplifies testing and addressing the feedback.
Othewise, switching all base to use netlink at once may be too big of a leap.
This change targets amd64, the other architectures will follow soon.

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
_ieee80211_free_node() the new __ieee80211_free_node().
Add IEEE80211_DEBUG_REFCNT to the NOTES file on amd64 to keep exercising
the option.

While uart could be detected completely through plug and play means, add
it here for two reasons. First, we don't do that from the loader, so
it's not available as a console. Second, even if we did do it from the
loader, there's a limitation in the system today that console drivers
must be compiled into the kernel because the console is selected before
external modules are linked into the kernel. Adding it only increases

The MINIMAL configs were overlooked. They are compiled as part of
universe, so this broke universe builds. Add the same defafults as for
GENERIC.
Sponsored by: Netflix
NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.
