[PATCH net 6/9] virtio-net: make rx buf size estimation works for XDP

2016-12-23 Thread Jason Wang

We don't update ewma rx buf size in the case of XDP. This will lead underestimation of rx buf size which causes host to produce more than one buffers. This will greatly increase the possibility of XDP page linearization. Cc: John Fastabend Signed-off-by: Jason Wang
