This entirely depends on the user, and the values are set using ethtool. $ ethtool -C <interface> tx-frames X rx-frames Y rx-usecs Z tx-usecs W > Bytes = time. Packets nowadays have a dynamic range of 64-64k bytes, > and with big TCP even more. would there be any way to use > bytes rather than packets? This feature should follow the VirtIO spec. The parameters are set with ethtool, so we should use the defined ethtool parameters. The parameters are set with the virtnet_set_coalesce function, which is the ethtool_ops set_coalesce callback.
