In a similar vein, many operating systems have support for a number of network cards, a common example being the e1000 card on the PCI bus. The best practice from VMware is to use the VMXNET3 Virtual NIC unless there is a specific driver or compatibility reason where it cannot be used. I'm currently working on various options from turning back the time via an AA or some magic (unlikely :-) ), or patching back to the old version (plus a few fixes that are needed for FTBFS) but also trying to shrink size on the new versions if that is reasonable. Bhyve can currently emulate two virtual NICs, namely virtio-net and e1000, and connect to the host network through two backends, namely tap and netmap. KVM modes: Software Simulation Mode - Linux. This was caused by providing the page_to_skb() function with an incorrect packet length in the driver's Rx path. This seems a little strange, esp.
