With the update to llvm 13 we are able to tell the compiler it can find
the SSP canary relative to the register that holds the userspace stack
pointer. As this is unused in most of the kernel it can be used here
to point to a per-thread SSP canary.
As the kernel could be built with an old toolchain, e.g. when upgrading
from 13, add a warning that the options was enabled but the compiler
doesn't support it to both the build and kernel boot.

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.

There is multiple reason for this :
- This makes it easier to see which driver is needed for each SoC
- This makes it easier to create a custom config for one SoC
- This really reduce boot time (which some people might want)
Some explaination about the files :
- std.arm64 contains all standard kernel option
- std.dev contains all the standard kernel devices
- std.<soc> contains all drivers needed to boot on this SoC family
- <SOC> includes std.arm64, std.dev and std.<soc>
- GENERIC includes std.arm64, std.dev and all std.<soc>

The r intc interrupt controller seems to do a lot of things :
- It can handle the NMI interrupt
- It have local interrupts for some device that also can be muxed with GIC
- It can serve as an forwarder for the GIC
It's mostly used for deepsleep/wakeup if I understood correctly and we do not
support this on arm64.
For now just forward everything to the GIC so interrupts works again for device

ENETC it a gigabit Ethernet controller found on the LS1028A board.
It supports basic VLAN offloads - tag extraction, injection and hardware
filtering. Inband MDIO connectivity is used for link status
monitoring through the miibus interface. Fixed-link mode is also
supported, which allows for operation of internal cpu to switch port.
Since no admin interrupts are present in hardware, link status polling
has to be used.
Due to a hardware bug software reset of the NIC results in a external
abort. Because of that most of the hardware initialization is done
during attach. This also means that in the case of an fatal error full
board reset is required.
The enetc_hw.h header was imporoted from Linux. It is dual licensed.

- Old hid_report_size() renamed to hid_report_size_max()
- New hid_report_size() calculates size of given report rather than
maximum size of all reports.
- hid_get_data_unsigned() renamed to hid_get_udata()
- hid_put_data_unsigned() renamed to hid_put_udata()

Ability to load-balance traffic over multiple path is a must-have thing for routers.
It may be used by the servers to balance outgoing traffic over multiple default gateways.
The previous implementation, RADIX_MPATH stayed in the shadow for too long.
It was not well maintained, which lead us to a vicious circle - people were using
non-contiguous mask or firewalls to achieve similar goals. As a result, some routing
daemons implementation still don't have multipath support enabled for FreeBSD.
Turning on ROUTE_MPATH by default would fix it. It will allow to reduce networking
feature gap to other operating systems. Linux and OpenBSD enabled similar support
at least 5 years ago.
ROUTE_MPATH does not consume memory unless actually used. It enables around ~1k LOC.
It does not bring any behaviour changes for userland.
Additionally, feature is (temporarily) turned off by the net.route.multipath sysctl
defaulting to 0.
