ifdata - get network interface info without parsing ifconfig output

SYNOPSIS

-p  Prints out the whole configuration of the interface.

-pe Prints "yes" or "no" if the interface exists or not.

-pa Prints the IPv4 address of the interface.

-pn Prints the netmask of the interface.

-pN Prints the network address of the interface.

-pb Prints the broadcast address of the interface.

-pm Prints the MTU of the interface.

Following options are Linux only.

-ph Prints the hardware address of the interface. Exit with a failure exit code if there is not hardware address for the given network interface.
