After upstream commit 5071034e4af7 ('neigh: Really delete an arp/neigh entry
on "ip neigh delete" or "arp -d"'), we could delete a single FAILED neighbour
entry now. But `ip neigh flush` still skip the FAILED entry.
Move the filter after first round flush so we can flush FAILED entry on fixed
kernel and also do not keep retrying on old kernel.

When modifying a route we set the RTA_OIF attribute only if a device was

earlier alternatively check also for the presence of "nexthop" keyword,
even though it has no effect. So remove the pointless check.

The original code which became rtnl_dump_done only shows netlink errors
if the protocol is NETLINK_SOCK_DIAG, but netlink dumps always appends
the length which contains any error encountered during the dump. Update
rtnl_dump_done to always show the error if there is one.
As an *example* without this patch, dumping a route object that exceeds
the internal buffer size terminates with no message to the user -- the
dump just ends because the NLMSG_DONE attribute was received. With this
patch the user at least gets a message that the dump was aborted.
$ ip ro ls
default via 10.0.2.2 dev eth0
10.0.2.0/24 dev eth0 proto kernel scope link src 10.0.2.15
10.10.0.0/16 dev veth1 proto kernel scope link src 10.10.0.1
172.16.1.0/24 dev br0.11 proto kernel scope link src 172.16.1.1
Error: Buffer too small for object
Dump terminated
The point of this patch is to notify the user of a failure versus
silently exiting on a partial dump. Because the NLMSG_DONE attribute
was received, the entire dump needs to be restarted to use a larger
buffer for EMSGSIZE errors. That could be done automatically but it
has other user impacts (e.g., duplicate output if the dump is
restarted) and should be the subject of a different patch.

Kernel now supports up to 30 labels but not defined as part of the uapi.
iproute2 handles up to 8 labels but in a non-consistent way. Update ip
to handle more labels, but in a more programmatic way.
For the MPLS address family, the data field in inet_prefix is used for
labels. Increase that field to 64 u32's -- 64 as nothing more than a
convenient power of 2 number.
Update mpls_pton to take the length of the address field, convert that
length to number of labels and add better error handling to the parsing
of the user supplied string.
