* pkt_sched: gen_estimator: Optimize gen_estimator_active()Jarek Poplawski2008-11-26
| | | | | | | | | | | | | Since all other gen_estimator functions use bstats and rate_est params together, and searching for them is optimized now, let's use this also in gen_estimator_active(). The return type of gen_estimator_active() is changed to bool, and gen_find_node() parameters to const, btw. In tcf_act_police_locate() a check for ACT_P_CREATED is added before calling gen_estimator_active(). Signed-off-by: Jarek Poplawski <jarkao2@gmail.com> Signed-off-by: David S.

* net: release skb->dst in sock_queue_rcv_skb()Eric Dumazet2008-11-26
| | | | | | | | | | | | | When queuing a skb to sk->sk_receive_queue, we can release its dst, not anymore needed. Since current cpu did the dst_hold(), refcount is probably still hot int this cpu caches. This avoids readers to access the original dst to decrement its refcount, possibly a long time after packet reception. This should speedup UDP and RAW receive path.

* net: Use a percpu_counter for orphan_countEric Dumazet2008-11-26
| | | | | | | | | Instead of using one atomic_t per protocol, use a percpu_counter for "orphan_count", to reduce cache line contention on heavy duty network servers. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Use a percpu_counter for sockets_allocatedEric Dumazet2008-11-26
| | | | | | | | | | | | | Instead of using one atomic_t per protocol, use a percpu_counter for "sockets_allocated", to reduce cache line contention on heavy duty network servers. Note : We revert commit (248969ae31e1b3276fc4399d67ce29a5d81e6fd9 net: af_unix can make unix_nr_socks visbile in /proc), since it is not anymore used after sock_prot_inuse_add() addition Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* tc: policing requires a rate estimatorStephen Hemminger2008-11-26
| | | | | | | | | | | | Found that while trying average rate policing, it was possible to request average rate policing without a rate estimator. This results in no policing which is harmless but incorrect. Since policing could be setup in two steps, need to check in the kernel.

* 8390: add common net_device opsStephen Hemminger2008-11-25
| | | | | | | | | | | | Fix the defactoring of ei_XXX functions in 8390 and 8390p. Remove the tx_timeout hack since no driver including the 3c503 overrides tx_timeout at this time, looks like a legacy thing. Also, since several drivers all have same hooks, provide common netdev_ops. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
