Manually editing etc/libnl/classid before adding tc objects is a pain.
This patch adds code to attempt auto generating a unique tc id which
will then be assigned to the provided name and added to the classid
file.
This will make the following commands work with prior definitions of
the names "top" and "test"
sudo sbin/nl-qdisc-add --dev eth0 --parent root --id top htb
sudo sbin/nl-class-add --dev eth0 --parent top --id test htb --rate 100mbit
It will generate the following ids automatically:
4001: top
4001:1 test
A database to resolve qdisc/class names to classid values and vice versa.
The function rtnl_tc_handle2str() and rtnl_tc_str2handle() will resolve
names automatically.
A CLI based tool nl-classid-lookup is provided to integrate the database
into existing iproute2 scripts.
