Thanks to Peter Bostroem from Google for drawing my attention to
this part of the code.
This fixes a bug which resulted in a warning on the userland

Remove also some unnecessary casts.

Add the SCTP_DETAILED_STR_STATS kernel option to control per policy
counters on every stream. The default is off and only an aggregated
counter is available. This is sufficient for the RTCWeb usecase.

in network byte order. Any host byte order processing is
done in local variables and host byte order values are
never[1] written to a packet.
After this change a packet processed by the stack isn't
modified at all[2] except for TTL.
After this change a network stack hacker doesn't need to
scratch his head trying to figure out what is the byte order
at the given place in the stack.
[1] One exception still remains. The raw sockets convert host
byte order before pass a packet to an application. Probably
this would remain for ages for compatibility.
[2] The ip_input() still subtructs header len from ip->ip_len,
but this is planned to be fixed soon.
