Is there a way
Are you actually using a netmap based application that acts as a packet router or is this just the vcxl interface running as a normal ifnet? > to increase the queues for the Chelsio nic, like the onboard igb ? If you're not running a netmap based router get rid of the num_vis=2 and simply try with the cxl0/cxl1 interfaces. They should each have 4 rxq/4 txq on your system. In case you want to increase the number of queues, use this: # cxl0/cxl1 etc. hw.cxgbe.nrxq10g=8 hw.cxgbe.ntxq10g=8 # vcxl0/vcxl1's "normal" queues hw.cxgbe.nrxq_vi=8 hw.cxgbe.ntxq_vi=8 # vcxl0/vcxl1's netmap queues hw.cxgbe.nnmrxq_vi=8 hw.cxgbe.nnmtxq_vi=8 Check in dmesg after you reboot with your new settings > vcxl0: 1 txq, 1 rxq (NIC); 1 txq, 1 rxq (TOE); 2 txq, 2 rxq (netmap) The "NIC" queues are the normal tx/rx queues, the "netmap" queues are active when the interface is in netmap mode. Does netsend generate a single flow or multiple flows? If it's a single flow it will use a single queue only.
