    # regexp pattern in dev_pat, an array that contains all the supported network
    # adapters. When found, the adapter type, the phandle and path name are saved 
    # in array variables. 
    #
    # The complicated part is that the full path name may be spread over more than
    # one line. Each line contains information about a node. If the supported 
    # network adapter is found on an nth level node, the full path name is the
    # concatenation of the node information from the 0th level to the nth level.
    # Hence, the path name from each level of the device tree needs to be saved.
    #
    # The pattern "\n(\[^\r]*)\r" is worth a second look. It took
    # many hours of debug and reading the expect book to get it right. When more
    # than one line of data is returned to expect at once, it is tricky getting
    # exactly one line of data to look at. This pattern works because it looks
    # for a newline(\n), any character other than a carriage return(\[^\r]*), and
    # then for a carriage return. This causes expect to match a single line.
    # If (.*) is used instead of (\[^\r]*), multiple lines are matched. (that was
    # attempt number 1)         
    #
    # Once a single line is found, it tries to determine what level in the device
    # tree this line is.  
    # searching through subsequent lines and subsequent levels until an 
    # adapter is found.  
    # The level of the current line, which
    # is calculated based on the assumption of "Level = (Leading Spaces - 1)/2".
    # Leading Spaces is the number of spaces between the first colon ':' and the
    # first non-space character of each line.
