DEVLINK_ATTR_ESWITCH_ENCAP_MODE netlink attribute carries enum. But the
code assumes bool value. Fix this by treating the encap mode in the same
way as other eswitch mode attributes, switching from "enable"/"disable"
to "basic"/"none", according to the enum. Maintain the backward
compatibility to allow user to pass "enable"/"disable" too. Also to be
in-sync with the rest of the "mode" commands, rename to "encap-mode".
Adjust the help and man page accordingly.

Extend bash-completion for two new commands:
devlink trap policer set DEV policer POLICER [ rate RATE ] [ burst BURST ]
devlink trap policer show DEV policer POLICER
And for "policer" / "nopolicer" parameters in existing command:
devlink trap group set DEV group GROUP [ action { trap | drop } ]
[ policer POLICER ] [ nopolicer ]

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
bytemode: off, dq_rate_estimator: off

PIE now uses per packet timestamps to calculate queuing
delay. The average dequeue rate based queue delay
calculation is now made optional. This patch adds the option
to enable or disable the use of Little's law to calculate
queuing delay.

Previously, the autocomplete routine did not complete actions after a
filter keyword, for example:
$ tc filter add dev eth0 u32 [...] action <TAB>
did not suggest the actions list, and:
$ tc filter add dev eth0 u32 [...] action mirred <TAB>
did not suggest the specific mirred parameters. Add the support for this
kind of completion by adding the _tc_filter_action_options routine and
invoking it from inside _tc_filter_options.

The action autocomplete routine (_tc_action_options) currently does not
support several actions statements in one tc command line as it uses the
_tc_once_attr and _tc_one_from_list.
For example, in that case:
$ tc filter add dev eth0 handle ffff: u32 [...] \
action sample group 5 rate 12 \
action sample <TAB>
the _tc_once_attr function, when invoked with "group rate" will not
suggest those as they already exist on the command line.
Fix the function to use the _from variant, thus allowing each action
autocomplete start from the action keyword, and not from the beginning of
the command line.

The _tc_one_of_list and _tc_once_attr functions simplfy the bash
completion task by validating each attr exist only once on the command
line.
For example, for the command line:
$ a b c d e
and the call to _tc_once_attr with "a f g", the function will suggest
"f g" as "a" existed in the command line in args 0.
Add the _from variant to those functions, which allows having the command
line option once from a specified index. In the previous example, calling
_tc_once_attr with 4 and "a f g" will suggest "a f g".

The sample tc action allows sampling packets matching a classifier. It
peeks randomly packets, and samples them using the psample netlink
channel. The user can specify the psample group, which the packet will be
sampled to, the sampling rate and the packet truncation (to save
kernel-user traffic).
The sampled packets contain informative metadata, for example, the input
interface and the original packet length.
The action syntax:
tc filter add [...] \
action sample rate <RATE> group <GROUP> [trunc <SIZE>]
[...]
Where:
RATE := The sampling rate which is the ratio of packets observed at the
data source to the samples generated
GROUP := the psample module sampling group
SIZE := optional truncation size
An example for a common usecase of the sample tc action: to sample ingress
traffic from interface eth1, one may use the commands:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff: \
matchall action sample rate 12 group 4
Where the first command adds an ingress qdisc and the second starts
sampling randomly with an average of one sampled packet per 12 packets
on dev eth1 to psample group 4.

Add function for command completion for tc in bash, and update Makefile
to install it under /usr/share/bash-completion/completions/.
Inside iproute2 repository, the completion code is in a new
`bash-completion` toplevel directory.
v2: Remove `if` statement in Makefile: do not try to install in
/etc/bash_completion.d/ if /usr/share/bash-completion/completions/
is not found; instead, the user can override the installation path
with the specific environment variable.
