Per RFC6437 stateful flow labels (e.g. labels set by flow label manager) cannot "disturb" nodes taking part in stateless flow labels. While the ranges only reduce the flow label entropy by one bit, it is conceivable that this might bias the algorithm on some routers causing a load imbalance. For best results on the Internet we really need the full 20 bits. Signed-off-by: Tom Herbert <tom@herbertland.com> --- net/ipv6/af_inet6.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
