Virtio-net supports "hardware" RSS with toeplitz key. Also, it allows receiving calculated hash in vheader that may be used with RPS. Added ethtools callbacks to manipulate RSS. Technically hash calculation may be set only for SRC+DST and SRC+DST+PORTSRC+PORTDST hashflows. The completely disabling hash calculation for TCP or UDP would disable hash calculation for IP. RSS/RXHASH is disabled by default. Changes since v1: * refactored virtnet_set_hashflow * refactored virtio_net_ctrl_rss * moved hunks between patches a bit Changes since rfc: * code refactored * patches reformatted * added feature validation Andrew Melnychenko (4): drivers/net/virtio_net: Fixed padded vheader to use v1 with hash. drivers/net/virtio_net: Added basic RSS support. drivers/net/virtio_net: Added RSS hash report. drivers/net/virtio_net: Added RSS hash report control. drivers/net/virtio_net.c | 383 +++++++++++++++++++++++++++++++++++++-- 1 file changed, 370 insertions(+), 13 deletions(-) -- 2.34.1 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
