    # 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

 PROCEDURE

 Declare procedure to obtain the list of valid adapter connector properties
 from the adapter card.  Connector types can be rj45, sc, 9pin, aui,
 bnc, or mic.  Speeds can be 10, 100, or 1000.  Duplex can be half or
 full.  This procedure will use the "supported-network-types"
 argument to the get-package-property command to get the list of
 properties for the given adapter.

 PROCEDURE

 Declare procedure to obtain the list of valid adapter connector properties
 from the adapter card.  Connector types can be rj45, sc, 9pin, aui,
 bnc, or mic.  Speeds can be 10, 100, or 1000.  Duplex can be half or
 full.  This procedure will use the "supported-network-types"
 argument to the get-package-property command to get the list of
 properties for the given adapter.

 PROCEDURE

 Declare procedure to obtain the list of valid adapter connector properties
 from the adapter card.  Connector types can be rj45, sc, 9pin, aui,
 bnc, or mic.  Speeds can be 10, 100, or 1000.  Duplex can be half or
 full.  This procedure will use the "supported-network-types"
 argument to the get-package-property command to get the list of
 properties for the given adapter.
