cdp-tools-1.0.ebuild

Hello

cdp-tools is a set of tools for working with the Cisco Discovery Protocol

The Cisco Discovery Protocol (CDP) is a proprietary layer 2 network protocol developed by Cisco Systems. It is useful for two reasons:
* getting information about the directly connected CDP devices such as the operating system version and IP address.
* checking that the OSI layer 2 connectivity is okay in case of IP (OSI layer 3) connectivity problems.
Enabling CDP on Linux systems can be interesting on routers like Quagga and Vyatta in a Cisco environment.

The package include two tools:
* cdp-send is used to send CDP traffic to directly connected devices.
* cdp-listen is used to receive CDP packets.

I am tested it on x86 with
net-libs/libpcap-1.1.1
net-libs/libnet-1.1.5
it works great.
