src/sys/arch/xen/xen: xennetback_xenbus.c
Log Message:
xennetback(4): Fix membars in xennetback_rx_copy_process.
- No need for barrier around touching req_cons and rsp_prod_pvt,
which are private.
- RING_PUSH_RESPONSES_AND_CHECK_NOTIFY already issues xen_wmb, no
need to add one explicitly.
- After pushing responses, must issue xen_wmb (not xen_rmb) before
hypervisor_notify_via_evtchn.
