Thanks, that gives me some context. I'm not familiar enough with dpdk.org c= odebase, so I wasn't aware of these issues. However, from the looks of it, = I doubt that vmxnet3 initialization would be affected - the RTE_PCI_DRV_NEE= D_IGB_UIO flag will be set regardless (in fact, the commit you linked to ha= s removed dependency on RTE_EAL_UNBIND_PORTS config option for vmxnet3), an= d vmxnet3 should initialize correctly just like the rest of the NICs with o= r without that config option. I am open to correction on that one however := -) Best regards, Anatoly Burakov DPDK SW Engineer -------------------------------------------------------------- Intel Shannon Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 Business address: Dromore House, East Park, Shannon, Co.
