Field Documentation

◆ TDPtrType

UINT8_t s_PXENV_UNDI_TBD::DataBlk::TDPtrType

Always 1.

A value of 0 would indicate that TDDataPtr were an ADDR32_t rather than a #SEGOFF16_t. The PXE specification version 2.1 explicitly states that this is not supported; TDDataPtr will always be a #SEGOFF16_t.

◆ TDRsvdByte

UINT8_t s_PXENV_UNDI_TBD::DataBlk::TDRsvdByte

Must be zero.

Definition at line 1040 of file pxe_api.h.

◆ TDDataLen

UINT16_t s_PXENV_UNDI_TBD::DataBlk::TDDataLen

Length of this transmit buffer.

Definition at line 1041 of file pxe_api.h.

◆ TDDataPtr

SEGOFF16_t s_PXENV_UNDI_TBD::DataBlk::TDDataPtr

Address of this transmit buffer.
