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

[Alessandro Marcolini <alessandromarcolini99@gmail.com>]

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).

Example:
The equivalent to:
# tc qdisc add dev eni1np1 root handle:1 ets bands 8 priomap 7 6 5 4 3 2 1 0

would be in ynl:
# ./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":8, "priomap":
[{"priomap-band":7}, {"priomap-band":6}, {"priomap-band":5},
{"priomap-band":4}, {"priomap-band":3}, {"priomap-band":2},
{"priomap-band":1}, {"priomap-band":0}]}}'

This patchset depends on the work done by Donald Hunter:

It is a modified version of a previous patch I've submitted, where I
removed the part already addressed by Donald and modified the rest
accordingly. Previous patch:
