They have\nbeen tested by intel QE which confirms the fix.\n\nIn this v3, only change is in the third patch, which aims at\navoiding race by assuming the application is not modifying\nthe rte_epoll_event once it has requested the enablement of the\ncorresponding interrupt. I tested this v3 with l3fwd-power\nexample.\n\nThanks to Intel QE team for all the validation work!\nMaxime\n\n\nMaxime Coquelin (3):\n vhost: fix guest notification setting\n net/vhost: fix queue update\n net/vhost: fix interrupt mode\n\n drivers/net/vhost/rte_eth_vhost.c | 93 +++++++++++++++++++++++--------\n lib/librte_vhost/vhost.c | 24 ++++++--\n lib/librte_vhost/vhost.h | 5 ++\n lib/librte_vhost/vhost_user.c | 11 +++-\n 4 files changed, 103 insertions(+), 30 deletions(-)" }
