Add ATF for unnumbered interfaces.

Move HIJACKING definition to net_common.sh

Add missing $NetBSD$ tag

branches: 1.1.2;
Add a new test case for PPPoE using PAP

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

Update test case.
The state of IPCP and IPv6CP is Closed when those are disabled.

Fix the wrong state check

After disconnection from PPPoE server, the client waits for
reconnection in initial state or reconnects in PADI state.

Add tests for "pppoectl {no}[ipcp|ipv6cp]"

Added missing '$'

branches: 1.29.2;
Added missing waiting for DAD completion

Added a test case for MTU of pppoe(4)

Make IFF_DEBUG enabled if $DEBUG is true

functionalize rump.ifconfig and pppoectl for clearer test code

Added test cases for "pppoectl passiveauthproto"

Use a state of IPCP and IPv6CP to wait for connection established

update test cases for AC-Name and Service-Name

Add test cases for AC-Name and Service-Name

Add a limit for auth at a test for invalid account

Fix typo

tests: use rump_server_add_iface to create interfaces

branches: 1.18.4;
Commonalize and add tests of creating/destroying interfaces

branches: 1.17.4;
Use the utility functions for rump_server

branches: 1.16.2;
add wait_for_disconnected to run_test() as well as run_test6().

Before commited MP-safe patch, IPv4 test can run in time without
wait_for_disconnected. Currently, wait_for_disconnected is required
because of locking overhead.

fix accidentally if_pppoe atf failure depends on cpu workload.

advised by s-yamaguchi@IIJ, thanks.

fix typo. ping6 deadline option is not "-w" but "-X".

fix accidentally if_pppoe atf failure depends on cpu workload.

Move HIJACKING definition to net_common.sh

fix: extend waittime to avoid unintended fail at high cpu load.

Accept DEBUG environment variable

By doing so, we can easily turn DEBUG on/off without modifying
the ATF scripts.

fix rarely rump.ping6 failures by "UDP connect". and fix typo.

Fix error when wait_for_session_established() is called without argument.

From Shoichi YAMAGUCHI<s-yamaguchi@IIJ>, Thanks.

Add new test cases(PAP and CHAP) for IPv6 PPPoE.

From Shoichi YAMAGUCHI<s-yamaguchi@IIJ>, Thanks.

Make sure to run cleanup

Should fix "tests: did not complete" failures.

Make test names self-descriptive

Disable rechallenge for chap test case.

NetBSD's PPPoE client doesn't support chap rechallenge yet.

From Shoichi YAMAGUCHI<s-yamaguchi@IIJ>, Thanks.

add a chap test; need to investigate what's wrong with it...

Add rumpdev library since we're now calling config_cfdriver_attach()

Should fix the newly-introduced test failure.
