The UNDI layer uses the NETDEV_IRQ_ENABLED flag to choose whether to return PXENV_UNDI_ISR_OUT_OURS or PXENV_UNDI_ISR_OUT_NOT_OURS for a given interrupt. For a network device that does not support interrupts, the flag will never be set and so pxenv_undi_isr() will always return PXENV_UNDI_ISR_OUT_NOT_OURS. This causes some NBPs (such as lpxelinux.0) to hang. Redefine NETDEV_IRQ_ENABLED as a simple administrative flag which can be set even on network devices that do not support interrupts. This allows pxenv_undi_isr() (which is the sole user of NETDEV_IRQ_ENABLED) to function as expected by lpxelinux.0.
