-----------> (One misspelling fixed.) Return non-zero tc_calc_xmittime() for rate tables While looking at the problem of HTB accuracy for high speed (~500Mbit rates) I've found that rate tables have cells filled with zeros for the smallest sizes. It means such packets aren't accounted at all. Apart from the correctness of such configs, let's make it safe with rather overaccounting than leaving it unlimited.
