The kernel guys fundamentally disagree with TCP offload: > http://www.linuxfoundation.org/en/Net:TOE I believe you are confusing TSO and LRO, which are stateless offloads (TCP connection state) with TOE (TCP Offload Engine) which is a statefull offload - TCP connection state kept in the card rather than the host stack. It is indeed true there is a considerable and likely to continue immune response in "netdev" to TOE, but they are quite pleased with stateless offloads like TSO and LRO. rick jones -- a wide gulf separates "what if" from "if only" these opinions are mine, all mine; HP might not want them anyway... :) feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
