|| ||implementation of IEEE 802.1Qbg in lldpad |

|| ||Article, Thread
this set of patches contains the initial implementation of the IEEE 802.1Qbg
standard: code for the exchange of EVB TLVs in LLDP frames to negotiate VSI
capabalities as well as VDP VSI TLVs between a host with virtual machines
and an adjacent switch.
It supports setting the parameters of the TLV exchange from the command
line using lldptool.
VDP profiles consisting of mode,mgrid,typeid,typeidversion,instanceid,mac,vlan
can be given to lldpad with lldptool or sent to lldpad via netlink messages from
the kernel or another program, e.g. libvirt.
VDP profiles are processed through the VDP/VSI and ECP state machines and
sent out in ECP frames.
ACK frames are received and processed through ECP and VDP/VSI state machines.
It implements a VDP bridge role for a port together with a lldptool command to
switch a port to the bridge role.
These patches apply against lldpad 0.9.38. Protocol debug messages are now logged
to syslog via LLDPAD_* macros and no longer to console. If you want to see them,
configure your syslog daemon to collect debug messages and start lldpad with -V 7.
Changes since last posting:
- fix to prevent parsing of TLVs across frame boundary
- fixed two minor memleaks in lldp_vdp_cmds.c and event_iface.c
- fixed typo
