[PATCH RESEND v2] vhost-net: set packet weight of tx polling to 2 * vq size

handle_tx will delay rx for tens or even hundreds of milliseconds when tx busy polling udp packets with small length(e.g. 1byte udp payload), because setting VHOST_NET_WEIGHT takes into account only sent-bytes but no single packet length. Ping-Latencies shown below were tested between two Virtual

[PATCH] vhost-net: add limitation of sent packets for tx polling

handle_tx will delay rx for a long time when tx busy polling udp packets with small length(e.g. 1byte udp payload), because setting VHOST_NET_WEIGHT takes into account only sent-bytes but no single packet length. Tests were done between two Virtual Machines using netperf(UDP_STREAM, len=1), then a

[PATCH] vhost-net: add time limitation for tx polling

handle_tx() will delay rx for a long time when busy tx polling udp packets with short length(ie: 1byte udp payload), because setting VHOST_NET_WEIGHT takes into account only sent-bytes but no time. It's not fair for handle_rx(), so needs to limit max time of tx polling. Signed-off-by: Haibin Zhang
