Title:
  VDE networking barely working

Status in QEMU:
  Expired

Bug description:
  Running qemu with a vde_switch and slirpvde:

    vde_switch -F -sock /tmp/qemu_vde_switch -M /tmp/qemu_vde_mgmt
    slirpvde -s /tmp/qemu_vde_switch -dhcp
    qemu-system-x86_64 -m 2048 -smp 2 -serial mon:stdio -display none -vga none -nodefaults -accel hax -net nic,macaddr=52:54:00:0e:e0:61,model=virtio -net vde,sock=/tmp/qemu_vde_switch -device virtio-rng-pci -drive file=worker.qcow2,if=virtio -drive file=cloud-init.iso,format=raw,if=virtio

  There is some network connectivity, ping and curl work, but bigger
  transfers like apt-get update or iperf break with the following errors
  printed in the output of vde_switch:

    vde_switch: send_sockaddr port 2: No buffer space available
    vde_switch: send_sockaddr port 2: No buffer space available
    vde_switch: send_sockaddr port 2: No buffer space available

  I've tried to change the MTU size and model of the adapter inside of
  the VM, but nothing worked.

  OS: macOS 10.15.2
  qemu: 4.2.0
  vde2 (vde_switch / slirpvde): 2.3.2
