bits. The motivation here is to eventually teach netisr and potentially other networking subsystems a bit more about how RSS work queues / buckets are configured so things have a hope of auto-configuring in the future. * net/rss_config.[ch] takes care of the generic bits for doing configuration, hash function selection, etc; * topelitz.[ch] is now in net/ rather than netinet/; * (and would be in libkern if it didn't directly include RSS_KEYSIZE; that's a later thing to fix up.) * netinet/in_rss.[ch] now just contains the IPv4 specific methods; * and netinet/in6_rss.[ch] now just contains the IPv6 specific methods. This should have no functional impact on anyone currently using the RSS support. Differential Revision: D1383 Reviewed by: gnn, jfv (intel driver bits)
