====== netinfo plugin ======

This plugin provides meta information about a network interface.

----

===== Functions =====

|netinfo::exists(device)|determine existence of network device|
|netinfo::hwaddr(device)|get hardware address (usually MAC address)|
|netinfo::ipaddr(device)|get IPv4 address|
|netinfo::netmask(device)|get netmask (IPv4) in long format like "255.255.255.0"|
|netinfo::netmask_short(device)|get netmask (IPv4) in short format like "/24" (for CIDR notation)
|netinfo::bcaddr(device)|get broadcast address (IPv4)|

'device' is a valid network device name, e.g. 'eth0' (do a 'cat /proc/net/dev' for valid names on your system)

===== Example =====

<code>
Widget IPaddress {
    class  'Text'
    expression netinfo::ipaddr('eth0').netinfo::netmask_short('eth0')
    prefix 'IP'
    width  20
    align  'R'
    update minute
}
</code>


This should show the IP address of device eth0 in 20 columns like
<code>
IP    192.168.0.2/24
</code>
