net/kni: reset rte_kni_conf struct before initialization
Checks
Commit Message
When kni driver calls eth_kni_start to start device, some fields such
as min_mtu and max_mtu of rte_kni_conf are not initialized. It will
cause kni_ioctl_create create a kni netdevice with a random min_mtu
and max_mtu value. This is unexpected and in some time we could not
change the kni device mtu with ip link command.
Fixes: ff1e35fb5f8 ("kni: calculate MTU from mbuf size")
