I didn't notice any parsing changes but might have glanced over this. >> Patch 11 updates the ACM documentation for this. >> Patch 12 fixes the inet_pton buffer space. >> Patch 13 fixes IPv6 support in acme. > > Relocated some common functionality into a static function and used > sockaddr_storage to store the resulting addresses. > >> Patch 14 adds the ability to preload the IPv4 and IPv6 destination caches. > > Name changes similar to those done for patch 10. > > addr_preload - indicates if the address data should be preloaded and the > format to use > addr_data_file - stores the file name containing the address data. The > default name is ibacm_addr.data. Nit: Default is ibacm_hosts.data rather than ibacm_addr.data. The one thing I noticed is that the check for using this (address) preload option without the previous (route) preload option was eliminated. This is probably the case in the long run but it is not the case with these current options. Should it be added back in ? >> Patch 15 adds a performance testing option to acme. > > Overall, the changes look good.

To restate this, it stems from address preload being host/IP to IB GID and route preload being GID and LID to PR so the later is needed first to populate the former (to PRs). > It would be nice if the address and routing preload data were more > independent, but that can be > added later, maybe, someday. Agreed. I'll keep this in mind in terms of future changes. -- Hal > - Sean > -- > To unsubscribe from this list: send the line "unsubscribe linux-rdma" in > the body of a message to [email protected] > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
