Since commit 82dc3c63 netif_napi_add() produces an error message if a NAPI poll weight greater than 64 is requested. qlcnic requests the weight as large as 256 for some of its rings, and smaller values for other rings. For instance in qlcnic_82xx_napi_add() I think the intention was to give the tx+rx ring a bigger weight than to rx-only rings, but it's actually doing the opposite. So I'm assuming the weights do not really matter much. Just use the standard NAPI weights for all rings.
