I missed the e1000 diffs. I'm ready to test anything I get to compile :-) Should be no problem for recent netmap diffs, since I'm running netmap from -current on 11.1 (I don't have spare hw for tests with -current unfortunate= ly). Short off topic request/question: Since if_vtnet(4) seems to support TSO/GSO, are there plans to provide these for virtio-net? Haven't used vritio-net anywhere else (KVm, XEN, etc.) but I used VMDQ on ESXi (together with vmx3f instead of if_vmx(4)) and the effici= ency is really impressive. Wish we could get at least a little closer :-) -harry --=20 You are receiving this mail because: You are the assignee for the bug.=
