First, this doesn't do any harm since CONFIG_IPV6_SCTP__ alone doensn't
result in anything getting compiled.

But besides, it seems a bit broken.

<-- snip -->

...

config IPV6_SCTP__
tristate
default y if IPV6=n
default IPV6 if IPV6

config IP_SCTP
tristate "The SCTP Protocol (EXPERIMENTAL)"
depends on IPV6_SCTP__
...

<-- snip -->

Semantically equivalent is the following for IPV6_SCTP__:

config IPV6_SCTP__
tristate
default y if IPV6=n || IPV6=y
default m if IPV6=m

If it was intended to disallow a static IP_SCTP with a modular IPV6 it
doesn't work: It's perfectly allowed to set IPV6=n and IP_SCTP=y and
later compile and install a modular IPV6 for the same kernel.

Could someone from the SCTP developers comment on the intentions behind
IPV6_SCTP__ ?
