|| ||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.
The patches have been rebased to lldpad 0.9.38 and still contain code to log
low-level protocol activity more verbosely than necessary.
In comparison to the last posted series, several changes have been made:
- all EVB TLV patches have been folded into one
- ECP and VDP implementation now only consists of 3 patches: ECP, VDP and VDP
- the protocol specific ecp structure has been moved away from the general
- the non-standard ECP_TX_IDLE state has been removed from the ECP TX state
machine which causes ecp frames to be sent out immediately to allow sequence
- VDP subtype has changed from 0 to 2
- some network byte order in the VSI tlv have been fixed
- vdp config variables are now saved in subsection "vdp" under the interface
- some compiler warnings have been fixed
- many other small bug fixes
