Unified TC attributes interface So far all common tc atttributes were accessed via specific functions, i.e. rtnl_class_set_parent(), rtnl_qdisc_set_parent(), rtnl_cls_set_parent() which implied a lot of code duplication. Since all tc objects are derived from struct rtnl_tc and these common attributes are already stored in there this patch removes all type specific functions and makes rtnl_tc_* attribute functions public. rtnl_qdisc_set_parent(qdisc, 10); becomes: rtnl_tc_set_parent((struct rtnl_tc *) qdisc, 10); This patch also adds the following new attributes to tc objects therefore removing them as tc specific attributes: - mtu - mpu - overhead This allows for the rate table calculations to be unified as well taking into account the new kernel behavior to take care of overhead automatically.

Unified TC API Finally got rid of all the qdisc/class/cls code duplication in the tc module API. The API takes care of allocation/freeing the tc object specific data. I hope I got it right this time.

fix includes after removing some headers commit f20bbe1f07fcff1509425884f5ed72ca8d5fb6ab Author: Thomas Graf <tgraf@suug.ch> Date: Tue Jan 22 19:10:38 2013 +0100 No longer install module API headers This commit causes a regression so no app using libnl can be compiled against it. This patch fixes it by removing includes of no-longe existing headers. Signed-off-by: Jiri Pirko <jiri@resnulli.us> Signed-off-by: Thomas Graf <tgraf@suug.ch>

classid auto generation if provided tc name does not exist 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
