Signed-off-by: Joe Damato <[email protected]> --- rfcv3: - Eliminated XDP checks; NAPIs will always be mapped to RX queues, as Gerhard Engleder suggested. v2: - Eliminate RTNL code paths using the API Jakub introduced in patch 1 of this v2. - Added virtnet_napi_disable to reduce code duplication as suggested by Jason Wang. drivers/net/virtio_net.c | 23 +++++++++++++++++++---- 1 file changed, 19 insertions(+), 4 deletions(-)
Looks good to me. I hope I didn't get you on the wrong track! Reviewed-by: Gerhard Engleder <[email protected]>
