From ad1ad5c8e36ea795034fcdac660b15d7c141d55b Mon Sep 17 00:00:00 2001 From: Susant Sahani Date: Sun, 23 Nov 2014 09:46:36 +0530 Subject: networkd: Introduce Link Layer Discovery Protocol (LLDP) This patch introduces LLDP support to networkd. it implements the receiver side of the protocol. The Link Layer Discovery Protocol (LLDP) is an industry-standard, vendor-neutral method to allow networked devices to advertise capabilities, identity, and other information onto a LAN. The Layer 2 protocol, detailed in IEEE 802.1AB-2005.LLDP allows network devices that operate at the lower layers of a protocol stack (such as Layer 2 bridges and switches) to learn some of the capabilities and characteristics of LAN devices available to higher layer protocols. --- src/libsystemd-network/lldp-port.h | 61 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 src/libsystemd-network/lldp-port.h (limited to 'src/libsystemd-network/lldp-port.h') diff --git a/src/libsystemd-network/lldp-port.h b/src/libsystemd-network/lldp-port.h new file mode 100644 index 0000000000..1b1ae040d1 --- /dev/null +++ b/src/libsystemd-network/lldp-port.h @@ -0,0 +1,61 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +/*** + This file is part of systemd. + + Copyright (C) 2014 Tom Gundersen + Copyright (C) 2014 Susant Sahani + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
