While iproute2 correctly uses ifinfomsg struct as the ancillary header
when requesting an FDB dump on old kernels, it sets the message type to
RTM_GETLINK. This results in wrong reply being returned.
Fix this by using RTM_GETNEIGH instead.
Before:
$ bridge fdb show brport dummy0
Not RTM_NEWNEIGH: 00000158 00000010 00000002
After:
$ bridge fdb show brport dummy0

AF_XDP is an address family that is optimized for high performance
packet processing.
This patch adds AF_XDP support to ss(8) so that sockets can be queried
and monitored.
Example:
$ sudo ss --xdp -e -p -m

Add RTNL_HANDLE_F_STRICT_CHK flag and set in rth flags to let know
commands know if the kernel supports strict checking.
Extracted from patch from Ido to fix filtering with strict checking
enabled.

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.

Add a filter option to rtnl_routedump_req and use it to set rtm_flags

ip l add dev tun type gretap external
ip r a 10.0.0.1 encap ip dst 192.168.152.171 id 1000 dev gretap
For gretap Key example when the command set the id but don't set the
TUNNEL_KEY flags. There is no key field in the send packet
In the lwtunnel situation, some TUNNEL_FLAGS should can be set by

NETLINK_DUMP_STRICT_CHK can be used for all GET requests,
dumps as well as doit handlers. Replace the DUMP in the

While most distributions long ago switched to the iproute2 suite
of utilities, which allow class-e (240.0.0.0/4) address assignment,
distributions relying on busybox, toybox and other forms of
ifconfig cannot assign class-e addresses without this kernel patch.
While CIDR has been obsolete for 2 decades, and a survey of all the
open source code in the world shows the IN_whatever macros are also
obsolete... rather than obsolete CIDR from this ioctl entirely, this
patch merely enables class-e assignment, sanely.

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.
