Fix locking issues in the pppol2tp driver which can cause a kernel
crash on SMP boxes. There were two problems:-

1. The driver was violating read_lock() and write_lock() scheduling
   rules because it wasn't using softirq-safe locks in softirq
   contexts. So we now consistently use the _bh variants of the lock
   functions.

2. The driver was calling sk_dst_get() in pppol2tp_xmit() which was
   taking sk_dst_lock in softirq context. We now call __sk_dst_get().

If an address family is not listed in "Supported Address Types"
parameter(INIT Chunk), but the packet is sent by that family, this
address family should be considered as supported by peer.  Otherwise,
an error condition will occur. For instance, if kernel receives an
IPV6 SCTP INIT chunk with "Support Address Types" parameter which
indicates just supporting IPV4 Address family. Kernel will reply an
IPV6 SCTP INIT ACK packet, but the source ipv6 address in ipv6 header
will be vacant. This is not correct.

refer to RFC4460 as following:
      IMPLEMENTATION NOTE: If an SCTP endpoint lists in the 'Supported
      Address Types' parameter either IPv4 or IPv6, but uses the other
      family for sending the packet containing the INIT chunk, or if it
      also lists addresses of the other family in the INIT chunk, then
      the address family that is not listed in the 'Supported Address
      Types' parameter SHOULD also be considered as supported by the
      receiver of the INIT chunk.  The receiver of the INIT chunk SHOULD
      NOT respond with any kind of error indication.

Here is a fix to comply to RFC.

Based upon a patch by Marcel Wappler:
 
   This patch fixes a DHCP issue of the kernel: some DHCP servers
   (i.e.  in the Linksys WRT54Gv5) are very strict about the contents
   of the DHCPDISCOVER packet they receive from clients.
 
   Table 5 in RFC2131 page 36 requests the fields 'ciaddr' and
   'siaddr' MUST be set to '0'.  These DHCP servers ignore Linux
   kernel's DHCP discovery packets with these two fields set to
   '255.255.255.255' (in contrast to popular DHCP clients, such as
   'dhclient' or 'udhcpc').  This leads to a not booting system.

If all of the entropy is in the local and foreign addresses,
but xor'ing together would cancel out that entropy, the
current hash performs poorly.

Suggested by Cosmin Ratiu:

	Basically, the situation is as follows: There is a client
	machine and a server machine. Both create 15000 virtual
	interfaces, open up a socket for each pair of interfaces and
	do SIP traffic. By profiling I noticed that there is a lot of
	time spent walking the established hash chains with this
	particular setup.

	The addresses were distributed like this: client interfaces
	were 198.18.0.1/16 with increments of 1 and server interfaces
	were 198.18.128.1/16 with increments of 1. As I said, there
	were 15000 interfaces. Source and destination ports were 5060
	for each connection.  So in this case, ports don't matter for
	hashing purposes, and the bits from the address pairs used
	cancel each other, meaning there are no differences in the
	whole lot of pairs, so they all end up in the same hash chain.
