[PATCH iproute2-next v3 0/8] iplink: Improve iplink_parse()

[Serhey Popovych <serhe.popovych@gmail.com>]

This is main routine to parse ip-link(8) configuration parameters.

Main reason to improve it is to pass network device @name, @dev and
other parameters to kind specific ->parse_opt() function so they can use
this information.

For example later we will extend iplink_get() to parse netlink
attributes deeper and replace open coded rtnl_talk() in ip/tunnel
modules to simplify getting existing tunnel information.

Among main change there is a number of patches to prepare for it
that improve iplink_parse() in some way.

See individual patch description message for more information.

v3
  Move vxlan/veth ifinfomsg save/restore to separate patch to
  make clear change that perform most of request buffer setups
  and checks in iplink_parse().

  Update commit message descriptions and extra new line from
  "utils: Introduce and use nodev() helper routine" patch.

v2
  Terminate via exit() when failing to parse command line arguments
  to help identify failing line in batch mode.

Thanks,
Serhii

Serhey Popovych (8):
  utils: Introduce and use nodev() helper routine
  iplink: Correctly report error when network device isn't found
  iplink: Use "dev" and "name" parameters interchangeable when possible
  iplink: Follow documented behaviour when "index" is given
  veth,vxcan: Save/reinitialize/restore whole @struct ifinfomsg
  iplink: Perform most of request buffer setups and checks in
    iplink_parse()
  iplink: Move data structures to block of their users
  iplink: Reduce number of arguments to iplink_parse()
