This command line is mixing a new style "-netdev" network
configuration option with an old-style "-net" one. This
probably won't work: you should either use only new-style
config options or only old-style config options.

New-style is either:
  -netdev id=foo,...  plus -device <some network device>,netdev=foo
  -nic ... (to set up an embedded network device that the board
   pre-creates for you)

Old-style is:
 -net nic -net user,... (the -net option is used both to say
  "give me an emulated ethernet device" and also "use the 'user',
  'tap', etc backends; you need to have two lots of -net, one
  for each part of this.)

https://wiki.qemu.org/Documentation/Networking may be helpful,
although it is a bit sparse on how to do new-style network
config with an embedded network device model.
