Member Data Documentation

Fragment

uint16_t tEoeHeaderDataUnion::Fragment

< Valid for EOE_TYPE_FRAME_FRAG and EOE_TYPE_TIMESTAMP_RES. Fragment sequence number within the current Ethernet frame (FRAME_FRAG only).

FrameNo

uint16_t tEoeHeaderDataUnion::FrameNo

Frame number correlating fragments to a single Ethernet frame.

OffsetBuffer

uint16_t tEoeHeaderDataUnion::OffsetBuffer

If Fragment != 0: byte offset of this fragment × 32. If Fragment == 0: total buffer size × 32 (FRAME_FRAG only).

Result

uint16_t tEoeHeaderDataUnion::Result

Result/status code for EOE_TYPE_INIT_RES and EOE_TYPE_MACFILTER_RES.

[struct]

struct { ... } tEoeHeaderDataUnion::v

Structured bit-field access for fragment and timestamp responses.
