This patch is to add TCA_TUNNEL_KEY_ENC_OPTS_ERSPAN's parse and
print to implement erspan options support in m_tunnel_key, like
Commit 6217917a38 ("tc: m_tunnel_key: Add tunnel option support
to act_tunnel_key") for geneve options support.
Option is expressed as version:index:dir:hwid, dir and hwid will
be parsed when version is 2, while index will be parsed when
version is 1. erspan doesn't support multiple options.
With this patch, users can add and dump erspan options like:
# ip link add name erspan1 type erspan external
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 protocol ip parent ffff: \
flower indev eth0 \
ip_proto udp \
action tunnel_key \
set src_ip 10.0.99.192 \

key_id 11
dst_port 6081

- print version, index, dir and hwid as uint.

Add ability to associate a policer with a trap group. The policer can be
unbound by using the 'nopolicer' keyword. In which case, the value

This patch adds support for the FQ-PIE packet Scheduler
Principles:
- Packets are classified on flows.
- This is a Stochastic model (as we use a hash, several flows might
be hashed to the same slot)
- Each flow has a PIE managed queue.
- Flows are linked onto two (Round Robin) lists,
so that new flows have priority on old ones.
- For a given flow, packets are not reordered.
- Drops during enqueue only.
- ECN capability is off by default.
- ECN threshold (if ECN is enabled) is at 10% by default.
- Uses timestamps to calculate queue delay by default.
Usage:
tc qdisc ... fq_pie [ limit PACKETS ] [ flows NUMBER ]
[ target TIME ] [ tupdate TIME ]
[ alpha NUMBER ] [ beta NUMBER ]
[ quantum BYTES ] [ memory_limit BYTES ]
[ ecn_prob PERCENTAGE ] [ [no]ecn ]
[ [no]bytemode ] [ [no_]dq_rate_estimator ]
defaults:
limit: 10240 packets, flows: 1024
target: 15 ms, tupdate: 15 ms (in jiffies)
alpha: 1/8, beta : 5/4
quantum: device MTU, memory_limit: 32 Mb
ecnprob: 10%, ecn: off

Add a new parameter '-Numeric' to show the number of protocol, scope,
dsfield, etc directly instead of converting it to human readable name.
Do the same on tc and ss.
This patch is based on David Ahern's previous patch.

Add nhid option for routes to use nexthop objects by id.
Example:
$ ip nexthop add id 1 via 10.99.1.2 dev veth1
$ ip route add 10.100.1.0/24 nhid 1
$ ip route ls
...
10.100.1.0/24 nhid 1 via 10.99.1.2 dev veth1

ctinfo is a tc action restoring data stored in conntrack marks to
various fields. At present it has two independent modes of operation,
restoration of DSCP into IPv4/v6 diffserv and restoration of conntrack
marks into packet skb marks.
It understands a number of parameters specific to this action in
additional to the usual action syntax. Each operating mode is
independent of the other so all options are optional, however not
specifying at least one mode is a bit pointless.
Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
[CONTROL] [index <INDEX>]
DSCP mode
dscp enables copying of a DSCP stored in the conntrack mark into the
ipv4/v6 diffserv field. The mask is a 32bit field and specifies where
in the conntrack mark the DSCP value is located. It must be 6
contiguous bits long. eg. 0xfc000000 would restore the DSCP from the
upper 6 bits of the conntrack mark.
The DSCP copying may be optionally controlled by a statemask. The
statemask is a 32bit field, usually with a single bit set and must not
overlap the dscp mask. The DSCP restore operation will only take place
if the corresponding bit/s in conntrack mark ANDed with the statemask
yield a non zero result.
eg. dscp 0xfc000000 0x01000000 would retrieve the DSCP from the top 6
bits, whilst using bit 25 as a flag to do so. Bit 26 is unused in this
example.
CPMARK mode
cpmark enables copying of the conntrack mark to the packet skb mark. In
this mode it is completely equivalent to the existing act_connmark
action. Additional functionality is provided by the optional mask
parameter, whereby the stored conntrack mark is logically ANDed with the
cpmark mask before being stored into skb mark. This allows shared usage
of the conntrack mark between applications.
eg. cpmark 0x00ffffff would restore only the lower 24 bits of the
conntrack mark, thus may be useful in the event that the upper 8 bits
are used by the DSCP function.
Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE]
[CONTROL] [index <INDEX>]
where :
dscp MASK is the bitmask to restore DSCP
STATEMASK is the bitmask to determine conditional restoring
cpmark MASK mask applied to restored packet mark
ZONE is the conntrack zone
CONTROL := reclassify | pipe | drop | continue | ok |
goto chain <CHAIN_INDEX>

Allow to limit 'ip xfrm {state|policy} list' output to a certain address
family and to delete all states/policies by family.
Although preferred_family was already set in filters, the filter
function ignored it. To enable filtering despite the lack of other
selectors, filter.use has to be set if family is not AF_UNSPEC.
