contains a list of transmit/receive statistics per receive queue basis.
Table E-1 Ethtool -S Option Statistics
Name Description
rx_crc_errors The number of packets dropped due to CRC errors.
rx_alignment_symbol_errors The number of packets dropped due to L1 alignment errors. This
counter is on a per-port basis.
rx_pause_frames The number of Ethernet pause frames (flow control) received.
rx_control_frames The number of control frames received.
rx_in_range_errors Received packets dropped when the Ethernet length field is not
equal to the actual Ethernet data length.
rx_out_range_errors Received packets dropped when their length field is >= 1501 bytes
and <= 1535 bytes.
rx_frame_too_long Received packets dropped when they are longer than 9216 bytes.
rx_address_filtered Received packets dropped when they don't pass the unicast or
multicast address filtering.
rx_dropped_too_small Received packets dropped when IP packet length field is less than the
IP header length field.
rx_dropped_too_short Received packets dropped when IP length field is greater than the
actual packet length.
rx_dropped_header_too_small Received packets dropped when the IP header length field is less
than 5.
rx_dropped_tcp_length Received packets dropped when the TCP header length field is less
than 5 or the TCP header length + IP header length is more than IP
packet length.
rx_dropped_runt Dropped receive packets due to runt packets (for example, packets
shorter than the Ethernet standard).
rxpp_fifo_overflow_drop,
rx_input_fifo_overflow_drop Number of received packets dropped when a FIFO for descriptors
going into the packet demux block overflows. In normal operation,
this FIFO must never overflow.
rx_ip_checksum_errs,
rx_tcp_checksum_errs,
rx_udp_checksum_errs Packets dropped due to TCP/IP/UDP checksum errors.
rx_switched_unicast_packets,
rx_switched_multicast_packets,
rx_switched_broadcast_packets The number of unicast, multicast, and broadcast packets switched
internally.
tx_pauseframes The number of Ethernet pause frames (flow control) transmitted per
port.
tx_controlframes The number of Ethernet control frames transmitted per port.
