|| ||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 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:
- ECP and VDP implementation patches have been merged. Now ECP/VDP only consists
of 2 patches: ECP/VDP and VDP commandline interface
- VDP sequence numbering has been fixed
- profile is removed in case VDP state machine reaches VSI_EXIT
- reduced debug verbosity in VDP code
- network byte order in sequence numbering was fixed
- fixed bug in profile comparison
- fixed default values for EVB supported mode and capabilities
- increased test coverage
- addressed John's comments on my last series
- many other small bug fixes
