From: Jian Shen <shenjian15@huawei.com> Currently, if user hasn't change channel number, the rss_size is limited to be no more than the vector number, in order to keep one vector only being mapped to one queue. But the queue number of each tc can be different, and one vector also can be mapped by multiple queues. So remove this limitation.
