mainline inclusion from mainline-v5.13-rc1 commit 5be36fb7855442e0299cf483d40457315a84cdf1 category: feature bugzilla: NA CVE: NA
----------------------------
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.
