route.c uses newroute() to handle the "route get" command. The logic
inside newroute() adds RTF_GATEWAY flag if "-interface" flag is not
specified. That results in the inconsistent RTM_GET message with
RTF_GATEWAY set but no RTAX_GATEWAY provided. Address this in the
translation code by checking if the gateway is actually provided.
Handle data-lanes property for pcie phy and set it accordingly.
This makes devices attached to pcie3 work properly.
For some RK3568 based boards, RTL8125B based device is
connected it. So with this, realtek-re-kmod driver attaches
and works.
Partially obtained from OpenBSD.
Tested on NanoPI-R5S, FireFly Station P2 boards.

Different lagg protocols have different means and policies to process incoming
traffic. For example, for failover protocol, by default received traffic is only
accepted when they are received through the active port. For lacp protocol, LACP
control messages are tapped off, also traffic will be dropped if they are
received through the port which is not in collecting state or is not joined to
the active aggregator. It confuses if user dump and see inbound traffic on
lagg(4) interfaces but they are actually silently dropped and not passed into
the net stack.
Tap traffic after protocol processing so that user will have consistent view of
the inbound traffic, meanwhile mbuf is set with correct receiving interface and
bpf(4) will diagnose the right direction of inbound packets.

From static code analysis, some device drivers (cxgbe, mlx4, mthca, and qlnx)
do not enter net epoch before lagg_input_infiniband(). If IPoIB interface is a
member of lagg(4) interface, and after returning from lagg_input_infiniband()
the receiving interface of mbuf is set to lagg(4) interface, then when
concurrently destroying the lagg(4) interface, there is a small window that the
interface gets destroyed and becomes invalid before infiniband_input() re-enter
net epoch, thus leading use-after-free.
Widen NET_EPOCH coverage to prevent use-after-free.

NETLINK is going to replace rtsock and a number of other ioctl/sysctl interfaces.
In-base utilies such as route(8), netstat(8) and soon ifconfig(8)
are being converted to use netlink sockets as a transport between
kernel and userland.
In the current configuration, it still possible have the kernel
without NETLINK (`nooptions NETLINK`) and use the aforementioned
utilies by buidling the world with `WITHOUT_NETLINK` src.conf knob.
However, this approach does not cover the cases when person unintentionally
builds a custom kernel without netlink and tries to use the standard userland.
This change adds `option NETLINK` to the default options for each
architecture, fixing the custom kernel issue.
For arm, this change uses `std.armv6` and `std.armv7` (netlink already in)
instead of DEFAULTS.

Since 81167243b the size of struct pfs_node is 280 bytes, so the kernel
memory allocator takes memory from 384 bytes sized bucket. However, the
length of the node name is mostly short, e.g., for Linux emulation layer
it is up to 16 bytes. The size of struct pfs_node w/o pfs_name is 152
bytes, i.e., we have 104 bytes left to fit the node name into the 256
bytes-sized bucket.

Heimdal's lib/hdb/db3.c is only built if DB3 is enabled, i.e. #if HAVE_DB3.
FreeBSD's bdb is DB1. Therefore the entire db3.c file is #ifdef'd out.
Let's avoid building a file that results in a useless object file.

Each physical port has an associated loopback tx channel and anything
transmitted over that channel by the driver is looped back internally by
the hardware as if received on that physical port. This change allows
tracing filters to be installed in this loopback path.

NFSv4.1/4.2 uses operation bitmaps for various operations,
such as the SP4_MACH_CRED case for ExchangeID.
This patch adds support for operation bitmaps so that
support for SP4_MACH_CRED can be added to the NFSv4.1/4.2
server in a future commit.
This commit should not change any NFSv4.1/4.2 semantics.

Split up the lhw lock and the scan lock. The latter is a mtx
while the former changes from mtx to sx as mac80211 downcalls may
sleep (and the ic lock is not usable in that case either and a larger
project to fix).
This will also enforce some lookups under lock (mostly scan) as well
as general protection for more compat code and avoid a possible
deadlock with one of the upcoming callbacks from driver into the
compat code.

The hang basically bricks a physical box and it can be recovered
only if you are able to boot from alternate media. This isn't a

Use the GICD_SIZE macro (0x10000), which is half the size of the current
fixed-sized mapping (128 * 1024 == 0x20000).
In ARM64 Hyper-V instances, it seems the Distributor's registers are
located immediately preceding a range of physical memory in the bus
address space. Thus, when ram0 is attaching and attempts to reserve
SYS_RES_MEMORY resources corresponding to its physmem ranges, it fails,
because the first 0x10000 bytes of this range are already owned by gic0.
