I've actually seen a similar problem with different NIC drivers, e.g. on RHEL6 running in ESXi 4 with the vmxnet3 drivers.

Both use e100e driver. So what you are actually saying, that NIC driver may handle it in a wrong way? If so, what are the possible reasons? How exactly you found out the driver ring frames size? Inserting printf() to the source or there is some more sane approach? - This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe. - This is the tcpdump-workers list.
