Agreed. However, when they start adding hooks to the ARP table, the routing table, and PMTU management, it begs the question what more is there to add for TOE (well, user-space driven TOE at least)? > Unfortunately I don't have more details, so you just get a generalized > rant :) OK, the patch under discussion here adds hooks to all the stuff in the previous paragraph for the purpose of RDMA over TCP (well I must say that the exact RDMA application/hardware has never been clearly given but this is what I can gather from the previous posts). Put it another way, I think the dividing line between TOE and iSCSI or virtualisation is exactly the interface between them and the Linux kernel. If the interface is an existing one such as SCSI or standard IP then it's OK. However, when it starts poking in the guts of the Linux stack I'd say that it has crossed the line.
