tecl_reset() is called from deactivate and qdisc is set to noop already, but subsequent teql_xmit does not know about it and dereference private data as teql qdisc and thus oopses. not catch it first :) Signed-off-by:

"struct proto" currently uses an array stats[NR_CPUS] to track change on 'inuse' sockets per protocol. If NR_CPUS is big, this means we use a big memory area for this. Moreover, all this memory area is located on a single node on NUMA machines, increasing memory pressure on the boot node. In this patch, I tried to : - Keep a fast !CONFIG_SMP implementation - Keep a fast CONFIG_SMP implementation for often used protocols (tcp,udp,raw,...) - Introduce a NUMA efficient implementation Some helper macros are defined in include/net/sock.h These macros take into account CONFIG_SMP If a "struct proto" is declared without using DEFINE_PROTO_INUSE / REF_PROTO_INUSE macros, it will automatically use a default implementation, using a dynamically allocated percpu zone. This default implementation will be NUMA efficient, but might use 32/64 bytes per possible cpu because of current alloc_percpu() implementation. However it still should be better than previous implementation based on stats[NR_CPUS] field. When a "struct proto" is changed to use the new macros, we use a single static "int" percpu variable, lowering the memory and cpu costs, still preserving NUMA efficiency. Signed-off-by:

Changes made on 18-sep to fix skb handling in the pppol2tp driver broke the transmit and receive paths. Users are only running into this now because distros are now using 2.6.23 and I must have messed up when I tested the change. For receive, we now do our own calculation of how much to pull from the skb (variable length L2TP header) rather than using skb_transport_offset(). Also, if the skb isn't a data packet, it must be passed back to UDP with skb->data pointing to the UDP header. For transmit, make sure skb->sk is set up because ip_queue_xmit() needs it.

The #idfed CONFIG_IP_MROUTE is sometimes places inside the if-s, which looks completely bad. Similar ifdefs inside the functions looks a bit better, but they are also not recommended to be used. Provide an ifdef-ed ip_mroute_opt() helper to cleanup the code. Signed-off-by:
