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.

sysfs keeps references to module parameters via /sys/module/*/parameters,
so marking them as __initdata can't work.
Steps to reproduce:

As the checksum verification is postponed till user calls recv or poll,

Grant Grundler was asking for more detail about correct usage of local

local_ops.txt.
"Please add a bit more detail. If DaveM is correct (he normally is), then
there must be limits on how the local_t can be used in the kernel process
and interrupt contexts. I'd like those rules spelled out very clearly
since it's easy to get wrong and tracking down such a bug is quite painful."
