Member Data Documentation

Info

uint16_t tEoeHeaderInfoUnion::Info

Raw 16-bit info word.

LastFragment

uint16_t tEoeHeaderInfoUnion::LastFragment

Non-zero if this is the last fragment of the Ethernet frame (FRAME_FRAG only).

PortAssign

uint16_t tEoeHeaderInfoUnion::PortAssign

Virtual port assignment (0 = unspecified, 1 = port 1).

Reserved

uint16_t tEoeHeaderInfoUnion::Reserved

Reserved; must be zero.

TimeStampAppended

uint16_t tEoeHeaderInfoUnion::TimeStampAppended

Non-zero if a 32-bit timestamp is appended after the last fragment (FRAME_FRAG with LastFragment = 1 only).

TimeStampRequested

uint16_t tEoeHeaderInfoUnion::TimeStampRequested

Non-zero if a timestamp response is requested by the sender (FRAME_FRAG only).

Type

uint16_t tEoeHeaderInfoUnion::Type

EoE message type identifier (e.g. FRAME_FRAG, INIT_REQ, MACFILTER_REQ).

[struct]

struct { ... } tEoeHeaderInfoUnion::v

Structured bit-field access.
