They have\nbeen tested by intel QE which confirms the fix.\n\nThe third patch fixes the interrupt regression. I tested it OK\nwith l3fwd-power use-case, but it has not been confirmed by Intel\nQE yet. The fix could be further improved in the future by\nintroducing a dedicated API in rte_epoll library to update epoll\nevents.\n\nThanks to Intel QE team for all the validation work!\nMaxime\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 | 61 ++++++++++++++++++++-----------\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, 72 insertions(+), 29 deletions(-)" }
