I think this is generally useful information. We actually used to report it but it was eliminated during the transition to Netlink because it was no longer strictly necessary (it was previously used to size buffers) and because it was grouped together with some other information that exposed too much in the way of implementation details. I think the place to put it is back where it originally was, which is in struct odp_stats. Stil we (still) haven't locked down the interface yet, it's OK to change the structure. My main goal in the process of locking down the userspace/kernel interface is to reduce the size and this generally simplifies things anyways. _______________________________________________ dev mailing list [email protected] http://openvswitch.org/mailman/listinfo/dev
