Hi all, I am wondering what exactly the rx_bytes and tx_bytes values exported under statistics/ in sysfs are supposed to represent.
Most popular ethernet drivers (8139too, e100, 3c59x) count the bytes in software, so they only take into account the bytes they actually send and receive. This excludes the 4-byte ethernet CRC if I understand correctly. Other drivers, on the other hand, get the transfered bytes statistics from hardware registers, and these appear to include the 4-byte CRC in the total count. This is the case of sk98lin and e1000, for example. So my question is, which drivers are right? Are we counting the emitted and received bytes at software level or at hardware level? Or do we just not care about the 4-byte/packet difference and both are acceptable?
