Problem reported by testing agency that RFC4861 section 6.2.5
states that a router should send an RA with a lifetime of 0
before ceasing to send RAs on the interface, or when the interace
is shutdown, or the router is shutdown. This fix adds that capability.

* evpn primary address advertisement

Problem reported by testing facility that our sending of Router

compliant with rfc4861. Added a knob to turn off fast retransmits
in order to meet the requirement of the RFC.

Further, they were originally only beings set
on ifdown and install. Extended their use into

We will use a nhe context for dataplane interaction with
nextho group hash entries.
New nhe's from the kernel will be put into a group array
if they are a group and queued on the rib metaq to be processed
later.
New nhe's sent to the kernel will be set on the dataplane context
with approprate ID's in the group array if needed.

Current autocompletion works only for simple "vrf NAME" case.
This commit expands it also for the following cases:
- "nexthop-vrf NAME" in staticd
- usage of $varname in many daemons
All daemons are updated to use single varname "$vrf_name".

zebra: inform upper layer error when reading correct speed interface
|
|
Start the conversion to allow zapi interface callbacks to be
controlled like vrf creation/destruction/change callbacks.
This will allow us to consolidate control into the interface.c
instead of having each daemon read the stream and react accordingly.
This will hopefully reduce a bunch of cut-n-paste stuff
Create 4 new callback functions that will be controlled by
lib/if.c
create -> A upper level protocol receives an interface creation event
The ifp is brand spanking newly created in the system.
up -> A upper level protocol receives a interface up event
This means the interface is up and ready to go.
down -> A upper level protocol receives a interface down
destroy -> A upper level protocol receives a destroy event
This means to delete the pointers associated with it.
At this point this is just boilerplate setup for future commits.
There is no new functionality.

When zebra gets a callback from the kernel that an interface has
actually been deleted *and* the end users has not configured
the interface, then allow for deletion of the interface from zebra.
This is especially important in a docker environment where containers
and their veth interfaces are treated as ephermeal. FRR can quickly
have an inordinate amount of interfaces sitting around that are
not in the kernel and we have no way to clean them up either.
My expectation is that this will cause a second order crashes
in upper level protocols, but I am not sure how to catch these
and fix them now ( suggestions welcome ). There are too many
use patterns and order based events that I cannot know for certain
that we are going to see any at all, until someone sees this problem
as a crash :( I do not recommend that this be put in the current
stabilization branch and allow this to soak in master for some time
first.

speed interface is done 15 seconds after interface creation. during that
time, the vrf or the interface may have disappeared. to protect this,
return an error in case it is not possible to create a vrf socket or it
is not possible to get speed of an interface because of a missing
device.

The code as written before this code change point would enqueue
every system route type to be refigured when we have an
interface event. I believe this was to originally handle bugs
in the way nexthop tracking was handled, mainly that if you keep
asking the question you'll eventually get the right answer.
Modify the code to not do this, we have fixed nexthop tracking
to not be so brain dead and to know when it needs to refigure
a route that it is tracking.

Initial commit of understanding interface speed changes
on startup was this commit:
dc7b3caefbd8baccb7fc3787a774e78d1a96636f
Effectively we had encountered situations on system startup
where the interface speed for a device was not properly setup
when zebra learns about the interface ( Imagine a bond being
brought up and the controlling software creating the bond
is not fast given system load, the bond's speed changes
upwards for each interface added ).
The initial workup on this was to allow a 15 second window
and then just reread the interface speed. We've since noticed
that under heavy system load on startup this is not always sufficient.
So modify the code to wait the 15 seconds and then check the interfaces
speed. If the interfaces speed is still MAX_UINT32T or it has changed
let's wait a bit longer and try again.

Field vrf_id is replaced by the pointer of the struct vrf *.
For that all other code referencing to (interface)->vrf_id is replaced.
This work should not change the behaviour.
It is just a continuation work toward having an interface API handling
vrf pointer only.
some new generic functions are created in vrf:
vrf_to_id, vrf_to_name,
a zebra function is also created:
zvrf_info_lookup
an ospf function is also created:
ospf_lookup_by_vrf
it is to be noted that now that interface has a vrf pointer, some more
optimisations could be thought through all the rest of the code. as
example, many structure store the vrf_id. those structures could get
the exact vrf structure if inherited from an interface vrf context.

the interface search is based on vrfs. As at startup, some interfaces
may be configured, there is need to have vrfs contexts present. A macro
is being appended with an extra parameter that permits create a vrf and
return the context. This macro is also used by some show routines, but
will not create vrfs, because that extra parameter will be set to false,
on that case.

Upon accessing interface NB API, the interface is created, if the vrf
is available. the commit does not change the behaviour, since at this
commit, this is not yet possible to have vrf contexts, while zebra did
not connect to daemons. However, that commit adds some work, so that it
will be possible to work on a vrf context, without having the vrf_id
completely resolved. for instance, if we suppose a vrf is created by
command 'vrf TOTO' in the starting configuration of a daemon, then 'interface
TITI vrf TOTO' will permit to create interface TITI within vrf TOTO.
the macro VRF_GET_INSTANCE will return the vrf context, if available or
not.

the vrf_id parameter is replaced by struct vrf * parameter.
this impacts most of the daemons that look for an interface based on the
name and the vrf identifier.
Also, it fixes 2 lookup calls in zebra and sharpd, where the vrf_id was
ignored until now.
