Hi, Keeping aside the fact as to why you wanna do this, the change needs to be done in PF driver that is on the host. XL710 uses i40e driver. So change the i40e.h file as below.
#define I40E_DEFAULT_QUEUES_PER_VF 4 To #define I40E_DEFAULT_QUEUES_PER_VF 16 Compile the driver and reinsert the kernel module.
