I don't think this is a good idea.

If you introduce sin6_scope_id into linux-2.2.x,
binaries on glibc-2.1 systems (including binaries
build on glibc-2.1 systems) encounter many random problem.

If you introduce sin6_scope_id into linux-2.2.x, sin6_scope_id
should take effect as of linux-2.4.x (usagi linux-2.2.x supports it)
to avoid any confusion.

Use linux-2.4.x (, or usagi linux-2.2.x).
