I think I was wrong here. I experimented using scapy by sending "Ether(src="00:00:00:00:00:02", dst="00:00:00:00:00:01")/Dot1Q(vlan=11)/IP(src="10.24.0.2", dst="10.24.0.1")/"payload"" and I saw the datapath flow installed with correct datapath port number. But I'm still not very sure what is the performance cost? Is that in that the using device driver can be faster than matching datapath flow? Besides sorry for this delayed review, the code makes sense and looks good to me, there is only one redundant line below On Tue, Jun 11, 2013 at 1:25 PM, Ben Pfaff <b...@nicira.com> wrote: > +ovs-appctl dpif/show > +ovs-appctl dpif/show | sed -n ' > +s/\./_/g > +s/^[[ ]]*\([[^ ]][[^ ]]*\) [[0-9]]*\/\([[0-9]]*\).*/\1=\2/p > +' > port-numbers > +cat port-numbers > +. ./port-numbers > The "+ovs-appctl dpif/show" is redundant.
