But driver modifies the weight to 1% for disabled TC and then set to hardware to make all TC work in DWRR mode. As a result, the total percent of all TC is more than 100%. Actually, this operation is also redundant, because these disabled TC will never be used. So this patch sets the weight of all TC based on user's configuration.
