Modified Files:
src/sys/arch/xen/xen: xennetback_xenbus.c
Log Message:
in xennetback_evthandler() just copy the DomU packet into destination
mbuf via hypervisor GNTTABOP_copy op instead of mapping the buffer into
Dom0 memory
no performance difference observed for now - it would probably make more
difference if Dom0 was MP, or when Dom0 is under VM pressure
this will eventually be updated to batch copy the DomU packets
