Hi,
I have just noticed that my NAS network card is getting some rx_missed errors, increasing quickly under heavy load from my PC to the NAS (1 Gb/s link through a Netgear switch between the 2).
Code
root@home-server:~# ethtool -S enp3s0
NIC statistics:
tx_packets: 3766795
rx_packets: 17095452
tx_errors: 0
rx_errors: 0
rx_missed: 35234
align_errors: 0
tx_single_collisions: 0
tx_multi_collisions: 0
unicast: 17092316
broadcast: 1875
multicast: 1261
tx_aborted: 0
tx_underrun: 0

But when I check the stats with ifconfig or other... no errors
Code
