RX packets:36957341 errors:0 dropped:21362 overruns:0 frame:0
Not sure but I'm seeing dramatically less now only 218 in the past 6 days
during 21.9GB of RX transfers
ethtool can provide more detail although they dont seen to add up to what
is shown by ifconfig
sudo ethtool -S eth0
NIC statistics:
tx_packets: 151768191

align_errors: 9634
tx_single_collisions: 0
tx_multi_collisions: 0
