Thanks, it appears this is the relevant bug? https://bugzilla.redhat.com/show_bug.cgi?id=854066 I did a test of this: # ethtool -k eth1 Features for eth1: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp-segmentation-offload: on udp-fragmentation-offload: off generic-segmentation-offload: on generic-receive-offload: on large-receive-offload: off rx-vlan-offload: on tx-vlan-offload: on ntuple-filters: off receive-hashing: off and the problem did not appear to go away.
