Karl sorry to over flood you with questions... - what is the pci3p1 interface? - Is this the broadcom or or the Intel interface? - Are you using PF_RING from SVN (I mean 4.7.0) ? - Can you send me the output of "ethtool -S pci3p1" ? - Do you have this issue also with other interface types? - are you using the sock of the PF_RING-aware drivers?
