-/**
- * Poll for received packets

- * @v netdev Network device
- *
- * Fun, fun, fun. UNDI drivers don't use polling; they use
- * interrupts. We therefore cheat and pretend that an interrupt has
- * occurred every time undinet_poll() is called. This isn't too much
- * of a hack; PCI devices share IRQs and so the first thing that a
- * proper ISR should do is call PXENV_UNDI_ISR to determine whether or
- * not the UNDI NIC generated the interrupt; there is no harm done by
- * spurious calls to PXENV_UNDI_ISR. Similarly, we wouldn't be
- * handling them any more rapidly than the usual rate of
- * undinet_poll() being called even if we did implement a full ISR.
- * So it should work. Ha!
- *
- * Addendum (21/10/03). Some cards don't play nicely with this trick,
- * so instead of doing it the easy way we have to go to all the hassle
- * of installing a genuine interrupt service routine and dealing with
- * the wonderful 8259 Programmable Interrupt Controller. Joy.
- *
- * Addendum (10/07/07). When doing things such as iSCSI boot, in
- * which we have to co-operate with a running OS, we can't get away
- * with the "ISR-just-increments-a-counter-and-returns" trick at all,
- * because it involves tying up the PIC for far too long, and other
- * interrupt-dependent components (e.g. local disks) start breaking.
- * We therefore implement a "proper" ISR which calls PXENV_UNDI_ISR
- * from within interrupt context in order to deassert the device
- * interrupt, and sends EOI if applicable.
