Instead of statically complaining about illegal inet address, use
get_family() to get the address family right.

Based on a patch by Hangbin Liu to print "inet6" for AF_INET6 made more
generic by me.

Add missing spaces around operators to increase readability. Aside from
that, make "preference" match a real synonym for "tos" and "dsfield" as
it's effect was identical to them.

This fixes a few syntax errors and changes route filter help text to use
classid instead of flowid to be consistent with other filters' help

If get_rt_realms() fails, try to get a possible raw u32 realms
value for the u32 RTA_FLOW/FRA_FLOW attribute, as it might be
useful to directly configure the hex value itself. And only if
that fails, then bail out.

The source realm is provided in the upper u16 (mask: 0xffff0000)
and the destination realm through the lower u16 part (mask:
0x0000ffff). This can be useful for tc's bpf realm matcher, but
also a full hex/mask param can be provided already for matching
through iptables' --realm cmdline option, for example.

Track upstream

This patch adds save and restore commands to "ip rule"
similar the same is made in commit f4ff11e3 for "ip route".

The feature is useful in checkpoint/restore for container
migration, also it may be helpful in some normal situations.

This has been inconsistent since the beginning of Git and seems to be
merely a documentation leftover, therefore just remove it from help

This patch adds support to parse and print lwtunnel
encapsulation attributes attached to routes for MPLS
and IP tunnels.

example:
Add ipv4 route with mpls encap attributes:

Examples:

  MPLS:
  $ ip route add 40.1.2.0/30 encap mpls 200 via inet 40.1.1.1 dev eth3
  $ ip route show
  40.1.2.0/30  encap mpls 200 via 40.1.1.1 dev eth3

  Add ipv4 multipath route with mpls encap attributes:
  $ ip route add 10.1.1.0/30 nexthop encap mpls 200 via 10.1.1.1 dev eth0 \
		    nexthop encap mpls 700 via  40.1.1.2 dev eth3
  $ ip route show
  10.1.1.0/30
    nexthop encap mpls 200  via 10.1.1.1  dev eth0 weight 1
    nexthop encap mpls 700  via 40.1.1.2  dev eth3 weight 1

  IP:
  $ ip route add 10.1.1.1/24 encap ip id 200 dst 20.1.1.1 dev vxlan0

This patch introduces two new api's rta_nest and rta_nest_end to
nest attributes inside a rta attribute represented by 'struct rtattr'
as required to construct a nexthop. Also adds rta_addattr* variants
for u8, u16 and u64 as needed to support encapsulation.
