fq_codel: fix TCA_FQ_CODEL_DROP_BATCH_SIZE sanity checks
My intent was to not let users set a zero drop_batch_size, it seems I once again messed with min()/max(). Fixes: 9d18562a2278 ("fq_codel: add batch ability to fq_codel_drop()") Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Toke Høiland-Jørgensen <toke@redhat.com> Signed-off-by: David S.
