Add a -n (skip_config) flag that causes ncdevmem to skip NIC configuration when operating as an RX server. When -n is passed, ncdevmem skips configuring header split, RSS, and flow steering, as well as their teardown on exit. This allows ksft tests to pre-configure the NIC in the host namespace before launching ncdevmem in the guest namespace. This is needed for netkit devmem tests where the test harness namespace has direct access to the NIC and the ncdevmem namespace does not.
