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.

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.

Allow to set the DF bit behaviour for outgoing IPv4 packets: it can be
always on, inherited from the inner header, or, by default, always off,
which is the current behaviour.
v2:
- Indicate in the man page what DF refers to, using RFC 791 wording

This is simpler and cleaner, and avoids having to include the header
from every file where the functions are used. The prototypes of the
internal implementation are in this header, so utils.h will have to be
included anyway for those.

Stephen converted macsec's sci to use 0xhex, but 0xhex handles
unsigned int's, not 64 bits ints. Thus, the output of the "ip macsec
show" command is mangled, with half of the SCI replaced with 0s:
# ip macsec show
11: macsec0: [...]
cipher suite: GCM-AES-128, using ICV length 16
TXSC: 0000000001560001 on SA 0
# ip -d link show macsec0
11: macsec0@ens3: [...]
link/ether 52:54:00:12:01:56 brd ff:ff:ff:ff:ff:ff promiscuity 0
macsec sci 5254001201560001 [...]
where TXSC and sci should match.
