This patch fixes incorrect -EINVAL errors due to invalid

$ip -f mpls route add 100 as 200 via inet 10.1.1.2 dev swp1
$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1
$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1
RTNETLINK answers: Invalid argument
$ip -f mpls route del 100
RTNETLINK answers: Invalid argument
After patch:
$ip -f mpls route show
100 as to 200 via inet 10.1.1.2 dev swp1
$ip -f mpls route del 100 as 200 via inet 10.1.1.2 dev swp1
$ip -f mpls route show
Always set type to RTN_UNICAST for mpls route add/deletes.
Also to keep things consistent with kernel set scope to
RT_SCOPE_UNIVERSE for both mpls and ipv6 routes. Both mpls and ipv6 route
deletes ignore scope.

If a tunnel is created with a local address, you can't change it to any.
# ip tunnel add tunl1 mode ipip remote 10.16.42.37 local 10.16.42.214 ttl 64
# ip tunnel show tunl1
tunl1: ip/ip remote 10.16.42.37 local 10.16.42.214 ttl 64
# ip tunnel change tunl1 local any
# echo $?
0
# ip tunnel show tunl1
tunl1: ip/ip remote 10.16.42.37 local 10.16.42.214 ttl 64
It happens that parse_args zeroes ip_tunnel_parm, and when creating the
tunnel, it is OK to leave it as is if the address is any. However, when
changing the tunnel, the current parameters will be read from
ip_tunnel_parm, and local and remote address won't be zeroes anymore, so
it needs to be explicitly set to any.

If ip rule command fails talking to kernel, exit code should be 2.
The sub-command is called by cmd loop and the exit code is negative
of return value from the command callback.
If kernel complains about ip route request, exit status should be

Add a new option to toggle the ability of querying the RSS configuration of a specific VF.
VF RSS information like RSS hash key may be considered sensitive on some devices where
this information is shared between VF and PF and thus its querying may be prohibited by default.
This new option allows a system administrator with privileges to modify a PF state
to control if the above VF querying is allowed or not.
For example:
To enable RSS querying of VF[0] of ethX:
>> ip link set dev ethX vf 0 query_rss on

XFRM netlink family is independent from the route netlink family. It's wrong
to call rtnl_wilddump_request(), because it will add a 'struct ifinfomsg' into
the header and the kernel will complain (at least for xfrm state):

Two commands are added:
- ip netns list-id
- ip monitor nsid
A cache is also added to remember the association between the iproute2 netns
name (from /var/run/netns/) and the nsid.
To avoid interfering with the rth socket, a new rtnl socket (rtnsh) is used to
get nsid (we may send rtnl request during listing on rth).
Example:
$ ip netns list-id
nsid 0 (iproute2 netns name: foo)
$ ip monitor nsid
Deleted nsid 0 (iproute2 netns name: foo)
nsid 16 (iproute2 netns name: bar)

When creating an IPsec SA that sets 'proto any' (IPPROTO_IP) and
specifies 'sport' and 'dport' at the same time in selector, the
following error is issued:
"sport" and "dport" are invalid with proto=ip
However using IPPROTO_IP with ports is completely legal and necessary
when one wants to share the SA on both TCP and UDP. One of the
applications requiring sharing SAs is 3GPP IMS AKA authentication.

The kernel now has the capability to offload FDB and FIB entries to hardware.
It is important to let users know if table entries are also offloaded to
hardware. Currently offloaded FDB entries are indicated by the existence of
the flag 'external' on the entry as of the following commit:
commit 28467b7f3f
Author: Scott Feldman <sfeldma@gmail.com>
Date: Thu Dec 4 09:57:15 2014 +0100
bridge/fdb: add flag/indication for FDB entry synced from offload device
When the patch to add support for indicating that FIB entries were also
offloaded as posted to netdev by Scott Feldman it became clear that 'external'
would not be an ideal name for routes. There could definitely be confusion
about what this might mean since many routes are to external networks -- a
collision/confusion that did not happen with FDB.
Scott Feldman asked me to check with others and build concensus around a name.
After speaking with several people about this I am proposing we refer to both
FDB and FIB entries that are currently backed by hardware (based on the work
done in rocker) with the flag 'offload' appended to the end ofthe entry.
Some people liked the string 'external,' others liked 'hardware,' but the point
is to communicate that these routes are available to something that will will
offload the forwarding normally done by the kernel. Since the term 'offload'
is used so frequently it seems appropriate to use the same language in
ip/bridge output.
The term 'offload' also seems to resonate with many of the people who have
responded on Scott's original thread or to those who I reached out to directly
and did respond to my query, so it seems we have reached consensus that it
should be the term used going forward.

add a new command to configure the SPD hash table:
ip xfrm policy set [ hthresh4 LBITS RBITS ] [ hthresh6 LBITS RBITS ]
and code to display the SPD hash configuration:
ip -s -s xfrm policy count
hthresh4: defines minimum local and remote IPv4 prefix lengths of
selectors to hash a policy. If prefix lengths are greater or equal
to the thresholds, then the policy is hashed, otherwise it falls back
in the policy_inexact chained list.
hthresh6: defines minimum local and remote IPv6 prefix lengths of
selectors to hash a policy, otherwise it falls back
in the policy_inexact chained list.
Example:
% ip -s -s xfrm policy count
SPD IN 0 OUT 0 FWD 0 (Sock: IN 0 OUT 0 FWD 0)
SPD buckets: count 7 Max 1048576
SPD IPv4 thresholds: local 32 remote 32
SPD IPv6 thresholds: local 128 remote 128
% ip xfrm pol set hthresh4 24 16 hthresh6 64 56
% ip -s -s xfrm policy count
SPD IN 0 OUT 0 FWD 0 (Sock: IN 0 OUT 0 FWD 0)
SPD buckets: count 7 Max 1048576
