Attaching an interface to a VRF is done by setting the interface's
master. Besides VRF, this can also be used for bridges.

Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
In order to preserve compatibility, the old 8-bit field: rtm_table is still
in use when table id is lower than 256.
Add support for the 32-bit table id (RTA_TABLE attribute) in:
- ip route print
- ip route modify
- ip rule print
- ip rule modify
Add printing of table ids to ip route.
Changes are compatible with the mainline iproute2 utilities.
These changes are required for compatibility with ConnMan, which by default
uses table ids greater than 255.

A padding to align a message should not only be added between
different attributes of a netlink message, but also at the end of the
message to pad it to the correct size.
Without this patch the following command does not work and returns an
error code:
ip link add type nlmon
Without this ip from busybox sends this:
sendmsg(3, {msg_name={sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000},
msg_namelen=12, msg_iov=[{iov_base={{len=45, ...},

msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 45
return value: 2
The normal ip utile from iproute2 sends this:

This patch ports the 'ip neigh' command, originally written by Alexey
Kuznetsov, <kuznet@ms2.inr.ac.ru>, to busybox.
The base of the port is the version of iproute that shipped with
Debian Squeeze, taken from:
http://http.debian.net/debian/pool/main/i/iproute/iproute_20100519.orig.tar.gz
This patch has actively been used by the Open Network Install
Environment (ONIE) project for over 3 years without incident.

iplink.c includes net/if_packet.h, which (on GLIBC)
only defines struct sockaddr_pkt. this struct is not
used anywhere in the code, and removing the #include
makes compilation succeed with musl libc.
