Description Ronald Wahl 2020-07-04 14:41:10 UTC
The Intel igc Ethernet driver does not provide any statistical info in /proc/net/dev:

$ cat /proc/net/dev
Inter-|   Receive                                                |  Transmit
 face |bytes    packets errs drop fifo frame compressed multicast|bytes    packets errs drop fifo colls carrier compressed
enp6s0:       0       0    0    0    0     0          0         0        0       0    0    0    0     0       0          0

But this interface is used by many tools for showing network utilization. Nevertheless some statistical counters are available via ethtool:

$ ethtool -S enp6s0
NIC statistics:
     rx_packets: 87554
     tx_packets: 39364
     rx_bytes: 122526287
     tx_bytes: 3043976
     rx_broadcast: 397
     tx_broadcast: 4
     rx_multicast: 2377
     tx_multicast: 84
     multicast: 2377

Is commit 6b7ed22ae4c9 ("igc: Fix returning wrong statistics") fixing this issue?
