iproute2 has been updated for the new strict policy in the kernel. Add a
helper to call setsockopt to enable the feature. Add a call to ip.c and
bridge.c
The setsockopt fails on older kernels and the error can be safely ignored
- any new fields or attributes are ignored by the older kernel.

Add a filter function to rtnl_addrdump_req to set device index in the
address dump request if the user is filtering addresses by device. In
addition, add a new ipaddr_link_get to do a single RTM_GETLINK request
instead of a device dump yet still store the data in the linfo list.

Similar to 'ip route' add the table id to the dump request for
kernel side filtering if it is supported.
Signed-off-by: David Ahern <dsahern@gmail.com>
Add protocol, table id and device to dump request if set in filter. If
kernel side filtering is supported it is used to reduce the amount of
data sent to userspace.
Older kernels do not parse attributes on a route dump request, so these
are silently ignored and ip will do the filtering in userspace.

Change nlmsg_len from sizeof(req) to use NLMSG_LENGTH on the header.
2 of the inner headers are not 4-byte aligned, so add a 0-length buf
after the header with the __aligned(NLMSG_ALIGNTO) to ensure the size
of the request is large enough. Use NLMSG_ALIGN in NLMSG_LENGTH to set

DECnet belongs in the history museum of dead protocols along
with Appletalk and IPX.
Linux support has outlived its natural life and the time has
come to remove it from iproute2. Dead code is a source
of bugs and exploits.
If anyone actually has DECnet running on some old distribution
they can just keep to the old version of iproute2.

Added support for filtering based on port ranges.
UAPI changes have been accepted into net-next.
Example:
1. Match on a port range:
-------------------------
$ tc filter add dev enp4s0 protocol ip parent ffff:\
prio 1 flower ip_proto tcp dst_port 20-30 skip_hw\
action drop
$ tc -s filter show dev enp4s0 parent ffff:
filter protocol ip pref 1 flower chain 0
filter protocol ip pref 1 flower chain 0 handle 0x1
eth_type ipv4
ip_proto tcp
dst_port 20-30
skip_hw
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 1 bind 1 installed 85 sec used 3 sec
Action statistics:
Sent 460 bytes 10 pkt (dropped 10, overlimits 0 requeues 0)

2. Match on IP address and port range:
--------------------------------------
$ tc filter add dev enp4s0 protocol ip parent ffff:\
prio 1 flower dst_ip 192.168.1.1 ip_proto tcp dst_port 100-200\
skip_hw action drop
$ tc -s filter show dev enp4s0 parent ffff:
