We had wrappers for IPv4 and IPv6 prefixes, but not for IP (version
agnostic) prefixes. This commit addresses this issue.

when a client disconnects, we iterate over the routing table to
remove any label that originated from that client. However we
were erroneously passing the route type to the function, while
it was expecting the lsp type. As a result, for example, killing
ldpd would not remove the ldp labels from the routes.
Kudos to @rwestphal for pointing me to the source of the issue.

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.

In preparation to Segment Routing:
- Update the management of Traffic Engineering subTLVs to the new tlvs parser
- Add Router Capability TLV 242 as per RFC 4971 & 7981
- Add Segment Routing subTLVs as per draft-isis-segment-routing-extension-25
Modified files:
- isis_tlvs.h: add new structure to manage TE subTLVs, TLV 242 & SR subTLVs
- isis_tlvs.c: add new functions (pack, copy, free, unpack & print) to process
TE subTLVs, Router Capability TLV and SR subTLVs
- isis_circuit.[c,h] & isis_lsp.[c,h]: update to new subTLVs & TLV processing
- isis_te.[c,h]: remove all old TE structures and managment functions,
and add hook call to set local and remote IP addresses as wellas update TE
parameters
- isis_zebra.[c,h]: add hook call when new interface is up
- isis_mt.[c,h], isis_pdu.c & isis_northbound.c: adjust to new TE subTLVs
- tests/isisd/test_fuzz_isis_tlv_tests.h.gz: adapte fuuz tests to new parser

in addition to non default vrf, once a new vrf is available, the static
daemon registers to events from that vrf, including presence of
interfaces. this permits to create static route with nexthop=interface.
Reversely, an unregistration is scheduled too when vrf disappears.

When processing route updates from the dataplane, we were
terminating the checking of nexthops prematurely, and we could

Anything we list in a xxx_SOURCES variable will be included for "make
tags", including filess marked as nodist_xxx_SOURCES. So if we don't
have Protobuf enabled, even though the entire library isn't built, "make
tags" will still try to process these files... which we can't
autogenerate because Protobuf is disabled. Same for gRPC.

If the interface doesn't exist in system, we'll default to broadcast and
then later not change that when the interface comes up. Explicitly
track whether the user configured the type and properly auto-set it if
they didn't.

This is annoying when editing a file and saving the file. IDEs like
VSCode can automatically remove trailing whitespaces, hence it would be better
having a clean code before pushing other changes.

The original check would always evaluate to false since
ISIS_PREFIX_SID_VALUE and ISIS_PREFIX_SID_LOCAL have different
values. Use !! to normalize the return value of the individual
checks to either 0 or 1, making the code do what was intended
(ensure the V/L flags are both 0 or 1).

when ever a FRR Client wants to send any data to another node
using MLAG Channel, uses below mechanisam.
1. sends a MLAG Registration to zebra with interested messages that
it is intended to receive from peer.
2. In response to this request, Zebra opens communication channel with
MLAG. and also in Rx. diretion zebra forwards only those messages which
client shown interest during registration
3. when client is no-longer interested in communicating with MLAG, client
posts De-register to Zebra
4. if this is the last client which is interested for MLAG Communication,
zebra closes the channel.
why PIM Needs MLAG Communication
================================
1. In general on LAN Networks elecetd DR will send the Join towards
Multicast RP in case of a LHR and Register in case of FHR.
2. But in case DR Goes down, traffic will be re-converged only after
the New DR is elected, but this can take time based on Hold Timer to
detect the DR down.
3. this can be optimised by using MLAG Mecganisam.
4. and also Traffic can be forwarded more efficiently by knowing the cost
towards RP using MLAG

There is a fairly common state we are seeing where watchfrr
has decided that something is not right and is printing out
a `wtf` message. At this point I am not sure what is going on
or how we are getting here, but let's add a bit more data dump
to the message so that we can figure out what is going on.
This is mainly being done because at this point in time I have no
clue the what/how of how we got here and I cannot reproduce.
Maybe by adding more useful information here I can figure out what is
going on.

RFC4271 specifies behavior when the hold timer is sent to zero - we
should not send keepalives or run a hold timer. But FRR, and other
vendors, allow the keepalive timer to be set to zero with a nonzero hold
timer. In this case we were sending keepalives constantly and maxing out
a pthread to do so. Instead behave similarly to other vendors and do not
send keepalives.
Unsure what the utility of this is, but blasting keepalives is
definitely the wrong thing to do.

User pass the string match large-community 1 exact-match from CLI.
Now route map lib has got the string as "1 exact-match". It passes the string
to call back for compilation. BGP will parse this string and came to know
that for "1" it has to do exact match. Routemap lib has to save "1" in it’s
dependency table. Here routemap is saving this as a “1 exact-match”
which is wrong. The solution is used the compiled data.
