Gro tcp

WebI took a mlx4 NIC, and fed it with big TCP packets (hacking GSO_MAX_SIZE) I added a hack into skb_gro_receive() to allow bigger GRO packets. I added a hack into ip6_rcv_core() to not trim skb based on ip6hdr->payload_len (Because GRO is not yet adding an exthdr) Basically, I did not add IPv6 exthdr with TLV_JUMBO yet, I made sure … WebHyper-V supports SR-IOV as a hardware acceleration option. If SR-IOV is enabled in both the vSwitch and the guest configuration, then the Virtual Function (VF) device is passed to the guest as a PCI device. In this case, both a synthetic (netvsc) and VF device are visible in the guest OS and both NIC’s have the same MAC address.
