tests: add tests for shmif

The test file is placed under tests/net, not tests/rump/rumpnet,
to leverage utility functions provided for tests in there.

branches: 1.41.2; 1.41.4;
tests: build and install added test files

tests: add tests for TCP with nc

tests: add tests for ALTQ CBQ

Add a new link-aggregation pseudo interface named lagg(4)

- FreeBSD's lagg(4) based implementation
- MP-safe and MP-scalable

branches: 1.37.2;
vether(4): Add ATF tests based on the tap(4) tests.

Clarify wg(4)'s relation to WireGuard, pending further discussion.

Still planning to replace wgconfig(8) and wg-keygen(8) by one wg(8)
tool compatible with wireguard-tools; update wg(4) for the minor
changes from the 2018-06-30 spec to the 2020-06-01 spec; &c. This just
clarifies the current state of affairs as it exists in the development
tree for now.

Mark the man page EXPERIMENTAL for extra clarity.

[ozaki-r] Changes to the kernel core for wireguard

add ipsec(4) interface ATF.

branches: 1.33.2;
merge the bouyer-socketcan branch to HEAD.

CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.

This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).

This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).

There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.

At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.

Add tests for ipsec

- Check if setkey correctly handles algorithms for AH/ESP
- Check IPsec of transport mode with AH/ESP over IPv4/IPv6
- Check IPsec of tunnel mode with AH/ESP over IPv4/IPv6

add l2tp(4) basic test.

branches: 1.30.2;
Add basic tests for vlan(4)

Add very basic tests for tun devices

branches: 1.28.2;
Add a new test case for PPPoE using PAP

From s-yamaguchi@IIJ (with some tweaks by me)

Add tests for tap(4)

add basic if_gif tests to ATF.

Add tests for NDP

Add tests for ARP

Forgot to commit this. Should fix the build.

Don't build tests that depend on RUMP if BSD_MK_COMPAT_FILE is defined.

Run mcast tests on rump kernels

The tests on anita qemus failed due to that the host network environment
didn't meet the tests.

The change makes the tests independent from host environments
and the tests will pass on any environments including anita qemus.

Discussed on tech-kern and tech-net.

MKRUMP=no fixes (Robert Swindells)

Port the in_cksum test from regress.

add a multicast test (what to do with v6?)

Add net/if_bridge test

Add bpfjit kernel tests for loading from mbuf chain.

branches: 1.16.2;
Merge riastradh-drm2 to HEAD.

Add a couple of basic IP/MPLS forwarding tests

branches: 1.14.2;
Enable tests which does not require rump if MKRUMP=no.
Pointed out by christos on source-changes-d.

ATF wrapping of the npf tests

branches: 1.12.2;
Build and install t_bpfilter.

add fdpass tests

Exclude tests that use rump

branches: 1.9.4;
Time to start adding tests for the routing code to make that part
of the kernel more approachable.

Begin the task with an xfail test for PR kern/40455.

branches: 1.8.2;
add test for PR kern/44369

convert program in PR kern/44054 to an atf test case

Add a most elementary carp test: it forks off two processes,
configures carp in each of them, and after verifying that the shared
address responds to ping it brutally kills the master like a proper
carnivore (none of that ifconfig down sissy vegan nonsense). Then
the test checks if the backup got its act together by pinging the
shared address and passes verdict.

Add xfail test for kernel diagnostic panic described in PR kern/43664

Get rid of static Atffiles and let bsd.test.mk generate them on the fly.

descend into icmp

Check that bpf doesn't accept programs with divide-by-zero in them.
Example filter from Guy Harris via PR kern/43185.

Add regression tests for low-port allocation in connect and listen, which
was broken and fixed recently in:
