From: Huisong Li <lihuis...@huawei.com>
hns3 PF driver enables one TC, allocates to 100% weight for this
TC and 0% for other disabled TC by default. 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.
