...is enabled - then clean tx before rx - fix: add missing braces in virtnet_freeze_down - testing: add 4KB TCP_RR + UDP test results Based on previous patchsets by Jason Wang: [RFC V7 PATCH 0/7] enable tx interrupts for virtio-net http://lkml.iu.edu/hypermail/linux/kernel/1505.3/00245.html Before commit b0c39dbdc204 ("virtio_net: don't free buffers in xmit ring") the virtio-net driver would free transmitted packets on transmission of new packets in ndo_start_xmit and, to catch the edge case when no new packet is sent, also in a timer at 10HZ.

From: Willem de Bruijn <willemb at google.com> Add napi for virtio-net transmit completion processing. Based on previous patchsets by Jason Wang: [RFC V7 PATCH 0/7] enable tx interrupts for virtio-net http://lkml.iu.edu/hypermail/linux/kernel/1505.3/00245.html Changes: RFC -> v1: - dropped vhost interrupt moderation patch: not needed and likely expensive at light load - remove tx napi weight - always clean all tx completions - use boolean to toggle tx-napi, instead - only clean tx in rx if tx-napi is enabled...
