not sure what you meant by 'dupulicate that check'.
If you're think about copy-pasting the whole 'if ((cfg->fc_flags & RTF_REJECT)'
check that it's not nice either.
If I read the patch correctly it's essentially initializing fib6_nh
and fib6_flags. Both are part of rt. So either pass both pointers
or pointer to rt. Why not?
