Subject: [SCTP]: Update SCTP_PEER_ADDR_PARAMS socket option to the latest api
 draft.

This patch adds support to set/get heartbeat interval, maximum number of
retransmissions, pathmtu, sackdelay time for a particular transport/
association/socket as per the latest SCTP sockets api draft11.

+ *                     field is empty all addresses for the association
+ *                     have heartbeats enabled upon them.

+ *                     SPP_HB_DISABLE - Disable heartbeats on the

+ *                     field is empty all addresses for the association
+ *                     will have their heartbeats disabled. Note also

+ *                     undetermined results.
+ *
+ *                     SPP_HB_DEMAND - Request a user initiated heartbeat
+ *                     to be made immediately.
+ *
+ *                     SPP_PMTUD_ENABLE - This field will enable PMTU
+ *                     discovery upon the specified address. Note that
+ *                     if the address feild is empty then all addresses
+ *                     on the association are effected.
+ *
+ *                     SPP_PMTUD_DISABLE - This field will disable PMTU
+ *                     discovery upon the specified address. Note that
+ *                     if the address feild is empty then all addresses

+ *                     results.
+ *
+ *                     SPP_SACKDELAY_ENABLE - Setting this flag turns
+ *                     on delayed sack. The time specified in spp_sackdelay
+ *                     is used to specify the sack delay for this address. Note
+ *                     that if spp_address is empty then all addresses will

From 90ddc4f0470427df306f308ad03db6b6b21644b8 Mon Sep 17 00:00:00 2001
From: Eric Dumazet
Date: Thu, 22 Dec 2005 12:49:22 -0800
Subject: [NET]: move struct proto_ops to const

I noticed that some of 'struct proto_ops' used in the kernel may share
a cache line used by locks or other heavily modified data. (default
linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
least)

This patch makes sure a 'struct proto_ops' can be declared as const,
so that all cpus can share all parts of it without false sharing.

This is not mandatory : a driver can still use a read/write structure
if it needs to (and eventually a __read_mostly)

I made a global stubstitute to change all existing occurences to make
them const.

This should reduce the possibility of false sharing on SMP, and
speedup some socket system calls.

From 14c850212ed8f8cbb5972ad6b8812e08a0bc901c Mon Sep 17 00:00:00 2001
From: Arnaldo Carvalho de Melo
Date: Tue, 27 Dec 2005 02:43:12 -0200
Subject: [INET_SOCK]: Move struct inet_sock & helper functions to
 net/inet_sock.h

To help in reducing the number of include dependencies, several files were
touched as they were getting needed headers indirectly for stuff they use.

Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
linux/dccp.h include twice.
