Merge branch 'net_sched-idr'

Chris Mi says:

====================
net/sched: Improve getting objects by indexes

Using current TC code, it is very slow to insert a lot of rules.

In order to improve the rules update rate in TC,
we introduced the following two changes:
        1) changed cls_flower to use IDR to manage the filters.
        2) changed all act_xxx modules to use IDR instead of
           a small hash table

But IDR has a limitation that it uses int. TC handle uses u32.
To make sure there is no regression, we add several new IDR APIs
to support unsigned long.

Addressed Hannes's comment:
express idr_alloc in terms of idr_alloc_ext and most of the other functions
