Given that statistics > are requested on an irregular basis, an overflow of the hardware counter > can go unnoticed. To count even very large numbers of multicast packets > reliably, add a software counter and remove previously applied code to > fill the multicast field requested by @rtl8169_get_stats64 with the values > read from the rx_multicast hardware counter. > > Signed-off-by: Corinna Vinschen <vinschen@...hat.com> Applied, thank you. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
