Dear Kohei, Thank you for your patch. Am 13.08.25 um 09:50 schrieb Kohei Enju:
Currently ethtool shows lbrx_packets and lbrx_bytes (Good RX
Packets/Octets loopback Count), but doesn't show the TX-side equivalents
(lbtx_packets and lbtx_bytes). Add visibility of those missing
statistics by adding them to ethtool statistics.
In addition, the order of lbrx_bytes and lbrx_packets is not consistent
with non-loopback statistics (rx_packets, rx_bytes). Therefore, align
the order by swapping positions of lbrx_bytes and lbrx_packets.
Tested on Intel Corporation I350 Gigabit Network Connection.
Before:
# ethtool -S ens5 | grep -E "x_(bytes|packets)"
rx_packets: 135
tx_packets: 106
rx_bytes: 16010
tx_bytes: 12451
lbrx_bytes: 1148
lbrx_packets: 12
After:
# ethtool -S ens5 | grep -E "x_(bytes|packets)"
rx_packets: 748
tx_packets: 304
rx_bytes: 81513
tx_bytes: 33698
lbrx_packets: 97
lbtx_packets: 109
lbrx_bytes: 12090
lbtx_bytes: 12401
