[PATCH V3 net-next 0/2] virtio-net: don't busy poll for cvq command
Hi all: The code used to busy poll for cvq command which turns out to have several side effects: 1) infinite poll for buggy devices 2) bad interaction with scheduler So this series tries to use cond_resched() in the waiting loop. Before doing this we need first make sure the cvq command is not executed in atomic environment, so we need first convert rx mode handling to a workqueue. Please

[PATCH 0/4] virtio-net: don't busy poll for cvq command
Hi all: The code used to busy poll for cvq command which turns out to have several side effects: 1) infinite poll for buggy devices 2) bad interaction with scheduler So this series tries to use sleep + timeout instead of busy polling. Please review. Thanks Changes since RFC: - switch to use BAD_RING in virtio_break_device() - check virtqueue_is_broken() after being woken up - use

In this version, I take a step back: the hardening part is not implemented and leave for future investigation. We use to aggree to use interruptible sleep but it

[PATCH net-next 1/3] virtio_net: set multicast filter list to host
The virtio_net driver never sends the multicast address list to the host. This is because send command takes a pointer to scatter list to send but only inserts that one entry into the outgoing scatter list. This bug has been there since: commit f565a7c259d71cc186753653d978c646d2354b36 Author: Alex Williamson <alex.williamson at hp.com> Date: Wed Feb 4 09:02:45 2009 +0000 virtio_net:
