do not force the safi to bee SAFI_EVPN and cause output
to be hosed.

As the prefix call function for mac handling has prefix_ prepended
before, the change must be propagated to all locations where those

Transmission and Reception routines have a part of code that is
conditionnally compiled to the usage of HAVE_EVPN. Also, each time a
subfield of prefix evpn is reached, like in configuration also, then a
conditionnaly compilation with HAVE_EVPN is used.

This commit fixes the nexthop display behaviour when an evpn entry is
matched. The commit handles both cases where IPv4 or IPv6 nexthop is
detected.

In case a manual set of MPLS, ENCAP, or EVPN entry is set, then the
nexthop attribute localted in attr->extra structure must be changed too.
In standard cases, where IPv4 IGP nexthop address is picked up, the same
address ie chosen.

A new vty command available under evpn address family. This command
takes following format:
(af-evpn)# [no] network <A.B.C.D/M|X:X::X:X/M> rd ASN:nn_or_IP-address:nn ethtag WORD
label WORD esi WORD gwip A.B.C.D routermac WORD
[route-map WORD]
Among new parameters, ethtag stands for the ethernet tag indentifier.
ESI stands for the ethernet segment identifier, and must be entered in
following format: 00:11:22:33:44:55:66:77:88:99.
gwip stands for the gateway IP address contained in RT5 message. A
check is done on that value since if gwip is ipv4, then ip prefix must
be ipv4. The same for ipv6.
RouterMAc is the gateway mac address sent as extended community
attribute.

This patch introduces show show bgp evpn commands to dump
NLRI entries configured or received on BGP, related to EVPN
New command introduced is the following:
show [ip] bgp l2vpn evpn [all | rd <rd name> ] [overlay]
Like for MPLS, similar set of commands is added for EVPN:
show [ip] bgp l2vpn evpn [all|rd <RDNAME>]
show [ip] bgp l2vpn evpn all neighbor <NEIGHBOR> routes
show [ip] bgp l2vpn evpn all neighbor <NEIGHBOR> advertised-routes

For each received routermac extended community, the mac address is
copied into routermac extended community context. For each emission,
a check is done against routermac extended community, if L2VPN is
enabled. If enabled, the extended community is appended.

As per draft-ietf-idr-tunnel-encaps-02, section 3.2.1, BGP Encap

appended to subtlv list, describing the vxlan network identifier to

The commit introduces the changes to be done to carry route type 5 EVPN
information in bgp extra attribute information. The commit also handles

gatewayIP and label information.

This patch introduces code to receive a NLRI message with route type
5, as defined in draft-ietf-bess-evpn-prefix-advertisement-02. It
It increases the number of parameters to extract from the NLRI and
to store into bgp extra information structure. Those parameters are
the ESI (ethernet segment identifier), the gateway IP Address (which
acts like nexthop attribute but is contained inside the NLRI itself)
and the ethernet tag identifier ( that acts for the VXLan Identifier)
This patch updates bgp_update() and bgp_withdraw() api, and then does the
necessary adapations for rfapi.
