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 commandline interface - the protocol specific ecp structure has been moved away from the general port structure - 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 synchronization - 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 in lldpad.conf - some compiler warnings have been fixed - many other small bug fixes For more information about lldpad take a look at http://sourceforge.net/projects/e1000/files/DCB%20Tools/lldpad/ Please review and comment. Thanks ! Jens
