This fixes the implementation in e062a8c11 ("pppoe: T5630: allow to specify MRU
in addition to already configurable MTU") and restores the bahavior that MRU
defaults to MTU if MRU is not explicitly set.
This was the behavior in VyOS 1.3.3 and below before we added ability to define
the MRU value.

Set the MRU (Maximum Receive Unit) value to n. PPPd will ask the peer to send
packets of no more than n bytes. The value of n must be between 128 and 16384,
the default was always 1492 to match PPPoE MTU.
A value of 296 works well on very slow links (40 bytes for TCP/IP header + 256
bytes of data). Note that for the IPv6 protocol, the MRU must be at least 1280.
CLI:
set interfaces pppoe pppoe0 mru 1280

Current state of vyos-1x smoketests have hardcoded features to test. The
feature support is inside the base class BasicInterfaceTest
class BasicInterfaceTest:
class TestCase(VyOSUnitTestSHIM.TestCase):
_test_dhcp = False
_test_ip = False
_test_mtu = False
_test_vlan = False
_test_qinq = False
_test_ipv6 = False
_test_ipv6_pd = False
_test_ipv6_dhcpc6 = False
_test_mirror = False
All derived classes need to enable the tests that are supported on this
interface type. Adding new feature to a given interface (like vif support in
T5237) require manually enabling those tests for the given interface.
It would make much more sense, if we can query the config backend for supported
interface options - or in other words - is there a CLI node available that
corresponds to set interfaces ethernet <name> vif - if that's the case,
_test_vlan = True.

Some ISPs seem to use the host-uniq flag to authenticate client equipment.
Add CLI option in VyOS to allow specification of the host-uniq flag.
set interfaces pppoe pppoeN host-uniq <value>

present for DHCP
VyOS 1.4 still leverages PPPd internals on the CLI.
pppd supports three options for a default route, none, auto, force.
* none: No default route is installed on interface up
* auto: Default route is only installed if there is yet no default route
* force: overwrite any default route
There are several drawbacks in this design for VyOS and the users. If auto is
specified, this only counted for static default routes - but what about dynamic
ones? Same for force, only a static default route got replaced but dynamic ones
did not got taken into account.
The CLI is changed and we now re-use already existing nodes from the DHCP
interface configuration:
* no-default-route:
On link up no default route is installed, same as the previous
default-route none
* default-route-distance:
We can now specify the distance of this route for the routing table on the
system. This defaults to 210 as we have for DHCP interfaces. All this will be
migrated using a CLI migration script.

Now that the PPPoE interface also makes use of the vyos.ifconfig.interface
class, we need to adjust the smoketests to reflect all those changes.
TODO:
Start a local PPPoE server in a namespace and connect locally for deeper
testing.
|
|
A validator is missing checking that if authentication is used on a PPPoE
interface, both username and password are set.
(cherry picked from commit 0361c3ac449f183476f7aee31439417d9f7f8012)

Currently every smoketest does the setup and destruction of the configsession
on its own durin setUp(). This creates a lot of overhead and one configsession
should be re-used during execution of every smoketest script.
In addiion a test that failed will leaf the system in an unconsistent state.
For this reason before the test is executed we will save the running config
to /tmp and the will re-load the config after the test has passed, always
ensuring a clean environment for the next test.

Commit bec29f31 ("dhcpv6-pd: pppoe: T2677: always restart daemon") used to
always restart the DHCPC6 client but the smoketest was not adjusted to this
change.

IPv6 enable can be considered once the ipv6 node is present!
