#define PXE_OPFLAGS_INTERRUPT_RECEIVE 0x0001
// Enable transmit interrupts. An external interrupt will be

// Enable command interrupts. An external interrupt will be
// generated when command execution stops.
#define PXE_OPFLAGS_INTERRUPT_COMMAND 0x0004
// Generate software interrupt. Setting this bit generates an
// externalinterrupt, if it is supported by the hardware.
