|Subject:||implementation of IEEE 802.1Qbg in lldpad|
|Date:||Tue, 28 Sep 2010 17:10:53 +0200|
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 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 For more information about lldpad take a look at http://sourceforge.net/projects/e1000/files/DCB%20Tools/l... Please review and comment. Thanks ! Jens
