Subject: [PATCH v4 net-next 0/3] Add support for encoding multi-attr to ynl

This patchset add the support for encoding multi-attr attributes, making
it possible to use ynl with qdisc which have this kind of attributes
(e.g: taprio, ets).

Patch 1 corrects two docstrings in nlspec.py
Patch 2 adds the multi-attr attribute to taprio entry
Patch 3 adds the support for encoding multi-attr

v1 --> v2:
- Use SearchAttrs instead of ChainMap

v2 --> v3:
- Handle multi-attr at every level, not only in nested attributes

v3 --> v4:
- Separate the new code block with empty lines

Some examples of what is now possible with the ynl cli:

- Add a taprio qdisc

# ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/tc.yaml \
  --do newqdisc --create --json '{
  "family":1, "ifindex":4, "handle":65536, "parent":4294967295, "info":0,
   "kind":"taprio",
   "stab":{
       "base": {
         "cell-log": 0,
         "size-log": 0,
         "cell-align": 0,
         "overhead": 31,
         "linklayer": 0,
         "mpu": 0,
         "mtu": 0,
         "tsize": 0
       }
   },
   "options":{
       "priomap": {
           "num-tc": 3,
           "prio-tc-map": "01010101010101010101010101010101",
           "hw": 0,
           "count": "0100010002000000000000000000000000000000000000000000000000000000",
           "offset": "0100020003000000000000000000000000000000000000000000000000000000"
       },
       "sched-clockid":11,
       "sched-entry-list": {"entry": [
           {"index":0, "cmd":0, "gate-mask":1, "interval":300000},
           {"index":1, "cmd":0, "gate-mask":2, "interval":300000},
           {"index":2, "cmd":0, "gate-mask":4, "interval":400000} ]
       },
       "sched-base-time":1528743495910289987, "flags": 1
   }
  }'


- Add an ets qdisc

# ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/tc.yaml --do newqdisc \
--create --json '{
"family":1, "ifindex":4, "handle":65536, "parent":4294967295, "kind":"ets",
"options":{
    "nbands":6,
    "nstrict":3,
    "quanta":{
        "quanta-band": [3500, 3000, 2500]
    },
    "priomap":{
        "priomap-band":[0, 1, 1, 1, 2, 3, 4, 5]
    }
}
}'
