* [lldp] Add support for the Link Layer Discovery ProtocollldpMichael Brown2023-02-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for recording LLDP packets and exposing TLV values via the settings mechanism. LLDP settings are encoded as ${netX.lldp/<prefix>.<type>.<index>.<offset>.<length>} where <type> is the TLV type <offset> is the starting offset within the TLV value <length> is the length (or zero to read the from <offset> to the end) <prefix>, if it has a non-zero value, is the subtype byte string of length <offset> to match at the start of the TLV value, up to a maximum matched length of 4 bytes <index> is the index of the entry matching <type> and <prefix> to be accessed, with zero indicating the first matching entry The <prefix> is designed to accommodate both matching of the OUI within an organization-specific TLV (e.g. 0x0080c2 for IEEE 802.1 TLVs) and of a subtype byte as found within many TLVs. This encoding allows most LLDP values to be extracted easily. For example System name: ${netX.lldp/5.0.0.0:string} System description: ${netX.lldp/6.0.0.0:string} Port description: ${netX.lldp/4.0.0.0:string} Port interface name: ${netX.lldp/5.2.0.1.0:string} Chassis MAC address: ${netX.lldp/4.1.0.1.0:hex} Management IPv4 address: ${netX.lldp/5.1.8.0.2.4:ipv4} Port VLAN ID: ${netX.lldp/0x0080c2.1.127.0.4.2:int16} Port VLAN name: ${netX.lldp/0x0080c2.3.127.0.7.0:string} Maximum frame size: ${netX.lldp/0x00120f.4.127.0.4.2:uint16} Originally-implemented-by: Marin Hannache <git@mareo.fr> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+1
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [build] Rename gPXE to iPXEMichael Brown2010-04-191-0/+36
Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.
