The driver supports many hw statistics. This patch supports dump statistics through ethtool_ops and ndo.get_stats64(). The type of hw statistics register is u32, To prevent the statistics register from overflowing, the driver dump the statistics every 5 minutes in a scheduled task.u32 allows the counter to reach 4294967295 before wrapping. So over 5 minutes, that is around 14,316,557 per second. Say this is your received byte counter? That means your line rate cannot be higher than 114Mbps? Is this device really only Fast Ethernet?

Haha, maybe my formula is wrong and I missed a unit conversion. Thank you very much for pointing out the error. I'll recalculate the correct value. Jijie Shao
