IT professionals may forgo jumbo frames in favor of NICs with large segment offload (LSO) and large receive offload (LRO) capabilities. LSO and LRO allow the CPU to transfer much larger quantities of data to (outbound) or from (inbound) the NIC with far less processing, essentially providing the same CPU performance benefit as jumbo frames.

Using TSO (TCP Segmentation Offload) and LRO (Large Receive Offload) on physical and virtual machine NICs improves the performance of ESX/ESXi hosts by reducing the CPU overhead for TCP/IP network operations.

Here is what VMware has on SRV-IO (Single Root I/O Virtualization):

Here are some suggestions for resolving poor network performance:

MLD (Multicast Listener Discovery) is used by IPv6 routers for discovering multicast listeners on a directly attached links.

Netflow is a networking protocol that collects IP traffic information.

So if you eliminate MLD and NetFlow, you are left with TSO, LRO and SRV-IO. SRV-IO eliminates some features from your VM though.
