Hello,
I'm using zc with ixgbe and RSS enabled (40 queues, one for each core) and I have noticed the following behavior:
1. When I execute tcpdump -i zc:eth0@39 (last queue) with no bpf-> I see no packets and the following in the summary stats:
0 packets captured
0 packets received by filter
101092 packets dropped by kernel
2. A similar behavior occurs when I execute: zc -i zc:eth0@39 :
Absolute stats: 0 pkts (12'293 drops) - 0 bytes
My question is: how come I can see drops in both tcpdump and zc's output but no actual packets ? what drops the packets and why ?
Thanks in advance,
Moshe
