You should totally join #bsdcode on efnet and ask me about it. :) on RSS, this is what would happen: * ALL NICs RSS BUCKET 0 -> core 0 * ... * ALL NICs RSS BUCKET 7 -> core 7 Now, that's not really 100% optimal for NUMA and multiple PCIe controllers, but we're not there yet. Hopefully I can twist/cajole navdeep @ chelsio to continue doing a little more RSS work so I can teach cxgbe/cxl about RSS configuration, but ixgbe, igb and ixl all do the above when RSS is enabled. -adrian
