In NetworkFile does not handle multiple addresses in [Network] section

[ghuband]

Using Python 3.5.
Fails to parse a network file with multiple "Address" entries in [Network]. Example:

File to parse:

[Match]
Name = br0

[Network]
DHCP = no
Address = 192.168.200.20/24
Address=192.168.1.188
Gateway=192.168.1.1

Code to parse:

# python3
Python 3.5.2 (default, Jul 17 2019, 17:56:15) 
[GCC 6.2.0] on linux

>>> from sysdfiles import NetworkFile
>>> nf=NetworkFile("/etc/systemd/network/br0.network")

    i, existing = IniFile.find_option(options, line.name)

    if line.name.lower() == name:
AttributeError: 'list' object has no attribute 'name'

Suggested fix:

    def find_option(options, name):
        name = name.lower()
        for i, line in enumerate(options):
            if isinstance(line, list):
                for j, lline in enumerate(line):
                    if lline.name.lower() == name:
                        return j, lline
            else:
                if line.name.lower() == name:
                    return i, line
        return -1, None
