Hi, 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: - implementation of VDP keepalive - better handling of response/reason codes by the switch - better handling of deassoc frame sent by switch - improved (human readable) printout of profile - bugfix to corrected wrong instance strlen - cleanup of vdp state machine - zero out unused part of ack frame - simplify handling of pending profile changes - simplify handling of response to libvirt - bugfix to prevent duplicate sending of TLVs For more information about lldpad take a look at http://sourceforge.net/projects/e1000/files/DCB%20Tools/lldpad/ Please review and comment.
