[Qemu-devel] [PATCH] linux-user: update netlink emulation

[Laurent Vivier]

Update enums with entries from linux 4.17

Translate entries that generate logs with iproute2 4.9.0 and
host kernel 4.15:

  # ip address show
  Unknown host QEMU_IFLA type: 43
  Unknown host QEMU_IFLA type: 43
  Unknown host QEMU_IFLA type: 43
  Unknown QEMU_IFLA_BR type 41
  Unknown QEMU_IFLA_BR type 42
  Unknown QEMU_IFLA_BR type 43
  Unknown QEMU_IFLA_BR type 44
  Unknown host QEMU_IFLA type: 43
  Unknown QEMU_IFLA_BR type 41
  Unknown QEMU_IFLA_BR type 42
  Unknown QEMU_IFLA_BR type 43
  Unknown QEMU_IFLA_BR type 44
  Unknown host QEMU_IFLA type: 43
