ipv6: Use ipv6_get_dsfield() instead of ipv6_tclass().
Commit 7a3198a8 ("ipv6: helper function to get tclass") introduced ipv6_tclass(), but similar function is already available as ipv6_get_dsfield(). We might be able to call ipv6_tclass() from ipv6_get_dsfield(), but it is confusing to have two versions. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.
