Hi Nayan,

That part should be independent from hardware,
RTE_KNI_REQ_CFG_NETWORK_IF sent whenever kni_net_open() called. And
ifconfig xxx up should cause kni_net_open() to be called.

KNI is virtual interface, and rte_kni is driver for it, the
request/response part is handled by rte_kni driver, so shouldn't differ
if DPDK port is 1G or 10G.

Do you debug and observe kni_net_open() not called or do you observe
ifconfig up is not working? If observed second, perhaps the reason can
be something else?
