    net: sched: introduce tcf block infractructure · 6529eaba
    Jiri Pirko authored
    Currently, the filter chains are direcly put into the private structures
    of qdiscs. In order to be able to have multiple chains per qdisc and to
    allow filter chains sharing among qdiscs, there is a need for common
    object that would hold the chains. This introduces such object and calls
    it "tcf_block".
    
    Helpers to get and put the blocks are provided to be called from
    individual qdisc code. Also, the original filter_list pointers are left
    in qdisc privs to allow the entry into tcf_block processing without any
    added overhead of possible multiple pointer dereference on fast path.
