OK, Christopher, how should we deal with this? I don't think defining
_KERNEL is a good idea. The only thing I can think of, if only s6_addr
is standard, is to change:
dst->in.sin_addr.s_addr = src->in6.sin6_addr.s6_addr32[3];
into taking the last 4 array elements of s6_addr and doing a shift of
24/16/8 to get an unsigned int32 value.
