NOTE: I am squashing several commits together because they
do not independently compile and we need this ability to
do any type of sane testing on the patches. Since this
series builds together I am doing this. -DBS
This new structure is the basis to get new link parameters for
Traffic Engineering from Zebra/interface layer to OSPFD and ISISD
for the support of Traffic Engineering
* lib/if.[c,h]: link parameters struture and get/set functions
* lib/command.[c,h]: creation of a new link-node
* lib/zclient.[c,h]: modification to the ZBUS message to convey the
link parameters structure
* lib/zebra.h: New ZBUS message
Signed-off-by: Olivier Dugeon <olivier.dugeon@orange.com>
Add support for IEEE 754 format
* lib/stream.[c,h]: Add stream_get{f,d} and stream_put{f,d}) demux and muxers to
safely convert between big-endian IEEE-754 single and double binary
format, as used in IETF RFCs, and C99. Implementation depends on host
using __STDC_IEC_559__, which should be everything we care about. Should
correctly error out otherwise.
* lib/network.[c,h]: Add ntohf and htonf converter
* lib/memtypes.c: Add new memeory type for Traffic Engineering support
Signed-off-by: Olivier Dugeon <olivier.dugeon@orange.com>
Add link parameters support to Zebra
* zebra/interface.c:
- Add new link-params CLI commands
- Add new functions to set/get link parameters for interface
* zebra/redistribute.[c,h]: Add new function to propagate link parameters
to routing daemon (essentially OSPFD and ISISD) for Traffic Engineering.
* zebra/redistribute_null.c: Add new function
zebra_interface_parameters_update()
* zebra/zserv.[c,h]: Add new functions to send link parameters
Signed-off-by: Olivier Dugeon <olivier.dugeon@orange.com>
Add support of new link-params CLI to vtysh
In vtysh_config.c/vtysh_config_parse_line(), it is not possible to continue
to use the ordered version for adding line i.e. config_add_line_uniq() to print
Interface CLI commands as it completely break the new LINK_PARAMS_NODE.

Update Traffic Engineering support for OSPFD
These patches update original code to RFC3630 (OSPF-TE) and add support of
RFC5392 (Inter-AS v2) & RFC7471 (TE metric extensions) and partial support
of RFC6827 (ASON - GMPLS).
* ospfd/ospf_dump.[c,h]: Add new dump functions for Traffic Engineering
* ospfd/ospf_opaque.[c,h]: Add new TLV code points for RFC5392
* ospfd/ospf_packet.c: Update checking of OSPF_OPTION
* ospfd/ospf_vty.[c,h]: Update ospf_str2area_id
* ospfd/ospf_zebra.c: Add new function ospf_interface_link_params() to get
Link Parameters information from the interface to populate Traffic Engineering
metrics
* ospfd/ospfd.[c,h]: Update OSPF_OPTION flags (T -> MT and new DN)
* ospfd/ospf_te.[c,h]: Major modifications to update the code to new
link parameters structure and new RFCs
