Beginning with kernel 2.6.37, it has been changed the meaning of dropped packet count. Before, dropped packets was most likely due to an error. Now, the rx_dropped counter shows statistics for dropped frames because of: Softnet backlog full Bad / Unintended VLAN tags Unknown / Unregistered protocols IPv6 frames when the server is not configured for IPv6, I’m seeing very high RX dropped packets in the output of ifconfig: Thousands of packets per second, an order of magnitude more than regular RX packets.. wlan0 Link encap:Ethernet HWaddr 74:da:38:3a:f4:bb inet addr:192.168.99.147 Bcast:192.168.99.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:31741 errors:0 dropped:646737 overruns:0 frame:0 TX.

We have multiple systems (Linux Servers) with these NICs. In each setup they are connected to a switch with a 40G port and we see no errors on the switch stats. We are using a 3m direct attach cable between the NIC and switch. What we also see is some systems are more prone to port. rx_dropped erro…
The ethtool statistics should be favoured over those of ifconfig . The dropped counter in ifconfig was originally intended to log protocol-only drops, such as a protocol handler being unable to allocate memory, but has since been obscured by various drivers adding their statistics in.
ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs 0 tx-usecs 0 4.3 Ring Size If you are seeing rx_dropped counters in ethtool -S ethX, or suspect cache pressure with multiple queues active, you might try adjusting the ring size from the default value. The default value is 512, the max is 4096.
