Hi all!

Here are some refactoring and fixes, mostly in net/tap.c I'm making on
my way to implementing TAP fd migration (through UNIX domain socket).

v4:
01-12: add r-b by Ben
10: fix bug in tap_parse_vhost_fds(), keep r-b

Vladimir Sementsov-Ogievskiy (13):
  net/af-xdp: fix type overflow
  net/tap: net_init_tap_one(): add return value
  net/tap: net_init_tap(): drop extra vhostfdname variable
  net/tap: net_init_tap(): refactor parameter checking
  net/tap: net_init_tap(): common fail label
  net/tap: net_init_tap_one() refactor to get vhostfd param
  net/tap: net_init_tap_one(): drop model parameter
  net: introduce net_parse_fds()
  net/tap: move fds parameters handling to separate functions
  net/tap: fix vhostfds/vhostfd parameters API
  net/tap: net_init_tap(): merge fd=, fds= and helper= cases into one
  net/tap: net_init_tap(): relax QEMU hubs check
  net/tap: check that user tries to define zero queues
