Subject: [NET_SCHED 05/05]: Kill CONFIG_NET_CLS_POLICE
[NET_SCHED]: Kill CONFIG_NET_CLS_POLICE
The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE,
remove the old code. The config option will be kept around to select
the equivalent NET_CLS_ACT options for a short time to allow easier
upgrades.
