The Statistics sub-menu provides you with an overview of all sent (tx) and received (rx) data packets:

Sent packets

tx-good: The number of successfully sent packets.
tx-unicast: The number of successfully sent unicast packets.
tx-broadcast: The number of successfully sent broadcast packets.
tx-multicast: The number of successfully sent multicast packets.
tx-lostcarrier: The number of lost carrier signals. Indicates a defective medium (for example, cable).
tx-deferred: The number of deferred packets. A packet is deferred if the MAC is busy sending another packet. Deferred packets do not indicate a problem, its just that the CPU queued a transmit packet during transmission of another packet
tx-collision: The number of colliding packets (max. 16).
tx-excesscol: The number of colliding packets (if tx-collision > 16).
tx-latecol: The number of colliding packets that require too much time to be transmitted. If a collision was detected after the 512th bit of the frame being transmitted was reached, a late collision is output.

Received packets

rx-good: The number of successfully received packets.
rx-unicast: The number of successfully received unicast packets.
rx-broadcast: The number of successfully received broadcast packets.
rx-multicast: The number of successfully received multicast packets.
rx-crc-err: The number of received CRC check-sum errors.
rx-align-err: The number of alignment errors (incorrect driver, cable defective) when receiving data packets.
rx-too-short: The number of data packets that are too short during the transmission.
rx-too-long: The number of data packets that are too long during the transmission.
rx-collision: The number of colliding packets (max. 16).
rx-overrun-err: The number of buffer overrun errors when receiving data packets.
rx-queue-overrun: The number of queue overrun errors when receiving data packets.
rx-no-buffer: The number of no buffers when receiving data packets.
rx-frame-dropped: The number of dropped frames. The reason is that the Ethernet driver has no handler for them. This could be because a non matching VLAN-tag, unsupported protocols (e.g. not IP4 IP6, ARP, RARP, PPPOED, PPPOES), etc.

Sent & Received Packets

rx-tx-64: The total number of sent and received packets of 64 Bytes.
rx-tx-64-127: The total number of sent and received packets of between 64 and 127 Bytes.
rx-tx-128-255: The total number of sent and received packets of between 128 and 255 Bytes.
rx-tx-256-511: The total number of sent and received packets of between 256 and 511 Bytes.
rx-tx-512-1023: The total number of sent and received packets of between 512 and 1023 Bytes.
rx-tx-1024: The total number of sent and received packets of 1024 Bytes.
