This means we can transmit a guest GSO packet directly into the host hardware, and receive fully reassembled LRO frames without artificially segmenting them. Unofficial testing against a ZC/L4RO capable backend show that we are supporting about 6.6Gb/s in throughput (vs 7.3Gb/s for native) which is up from the prior result of 5.7Gb/s without affecting our latency numbers. I will officially re-run my tests and update the graphs asap. http://developer.novell.com/wiki/index.php/AlacrityVM Kind Regards, -Greg --- Gregory Haskins (9): venet: add Layer-4 Reassembler Offload (L4RO) support venet: add a tx-complete event for out-of-order support venet: use an skblist for outstanding descriptors venet: add eventq protocol venet: cache the ringlen values at init venet: report actual used descriptor size venet: add pre-mapped tx descriptor feature venet: fix gso.hdr_len to report correct length venet: Update maintainer MAINTAINERS | 7 drivers/net/vbus-enet.c | 770 +++++++++++++++++++++++++++++++++++++++++++---- include/linux/venet.h | 61 +++- 3 files changed, 764 insertions(+), 74 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
