[ipxe-devel] undi_get_information->IntNumber : returned values

Hi Michael / iPXE community-
I have a question regarding the IntNumber returned to the bootloader - at 'pxenv_undi_get_information' - we have the following line:
( netdev_irq_supported ( pxe_netdev ) ? dev->desc.irq : 0 );
So in case the device have no IRQ supported the IntNumber is 0.
This IRQ 0 - is usually system timer.
1. Is it allowed (pxespec) to borrow this system timer as an interrupt ?
a. If not - what's the alternative (for non IRQ supporting device) - what should be returned in 'IntNumber' ?
