Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. I bet this has something to do with the way pktgen reuses skbs. Jiri, I presume the mac address 00:16:e6:54:8f:6f in the pktgen script was one of the guest interfaces? Or was it randomly selected to force a flood forward? (In reply to comment #4) > I bet this has something to do with the way pktgen reuses skbs. Jiri, I > presume the mac address 00:16:e6:54:8f:6f in the pktgen script was one of the > guest interfaces? Or was it randomly selected to force a flood forward? IIRC it was mac of different host. I did not change macs manually and this is not from virt pool. 0016E6 GIGA-BYTE TECHNOLOGY - looks like my home pc. ok, copy that, thanks *** Bug 722846 has been marked as a duplicate of this bug. *** sent upstream: http://marc.info/?l=linux-netdev&m=131110521220493&w=2 sent a new patch version upstream: http://marc.info/?l=linux-netdev&m=131162314207168&w=2 The upstream version has been comitted, I'll start backporting shortly. ugh, ABI issue. priv_flags is all used up in RHEL6. So I need to wait for Jiri's ABI fixups for the net_device struct to get integrated so that I can create an extended flag area.
