Hi Dmitry,
QEMU vmxnet3 produces the following warning with iPXE
(77f64b11f764e721f4f8704b7b90317e52d85fc3):
$ cd ~/ipxe/src
$ make bin/vmxnet3.rom
$ qemu-system-x86_64 -netdev user,id=netdev0 -device
vmxnet3,netdev=netdev0,romfile=bin/vmxnet3.rom
[vmxnet3][WR][vmxnet3_peer_has_vnet_hdr]: Peer has no virtio
extension. Task offloads will be emulated.
[vmxnet3][WR][vmxnet3_get_command_status]: Received request for
unknown command: cafe0002
The warning about virtio extensions is expected since I chose slirp networking.
iPXE does not show the NIC ('ifstat' command). I guess the driver
gave up during initialization:
https://git.ipxe.org/ipxe.git/blob/HEAD:/src/drivers/net/vmxnet3.c#l613
Any ideas?
Stefan
PS: I discovered this when testing net patches for the pull request I
just sent out. It's not a blocker, so vmxnet3 will finally be in
qemu.git/master very soon!
