static const uint32_t HWADDR_SOURCE_UNKNOWN
Used when actual origin is not known, e.g.
Definition: hwaddr.h:41
static const uint32_t HWADDR_SOURCE_RAW

Definition: hwaddr.h:44
static const uint32_t HWADDR_SOURCE_REMOTE_ID
A relay can insert remote-id.
Definition: hwaddr.h:63
static const uint32_t HWADDR_SOURCE_CLIENT_ADDR_RELAY_OPTION
Get it from RFC6939 option.
Definition: hwaddr.h:59
static const uint32_t HWADDR_SOURCE_IPV6_LINK_LOCAL
Extracted from IPv6 link-local address.
Definition: hwaddr.h:53
static const uint32_t HWADDR_SOURCE_DOCSIS_MODEM

Definition: hwaddr.h:79
static const uint32_t HWADDR_SOURCE_DUID
Extracted from DUID-LL or DUID-LLT (not 100% reliable as the client can send fake DUID).
Definition: hwaddr.h:48
static const uint32_t HWADDR_SOURCE_DOCSIS_CMTS
A CMTS (acting as DHCP relay agent) that supports DOCSIS standard can insert DOCSIS options that cont...
