[patch net-next 0/3] 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 also changed IDR to use
unsigned long. All clients of IDR are changed to use new IDR API.

Chris Mi (3):
  idr: Use unsigned long instead of int
  net/sched: Change cls_flower to use IDR
  net/sched: Change act_api and act_xxx modules to use IDR
