if_dealloc(9r)
NAME
  if_dealloc - Network: Frees the data structure previously allocated by
  if_alloc()

SYNOPSIS
  int if_dealloc(
	  struct ether_driver *ed );

ARGUMENTS
  ed  Specifies the address of the data structure previously allocated by
      if_alloc(). For network devices, this is the ether_driver data
      structure.

DESCRIPTION
  The if_dealloc() routine frees up the memory allocated by if_alloc(). This
  is only done if the ifnet data structure, assumed to be at the head of the
  data structure passed in, was not used in an if_attach() call. If it was
  used in an if_attach() call, then if_dealloc() ensures that the data
  structure is moved to the list of detached network interfaces.

RETURN VALUES
  ENODEV
      A NULL was passed in for ed.

  ESUCCESS
      The device was successfully decallocated or was found on the detached
      list.
