PXE ISR: Force polling on select hardware WORKAROUND
By OUI == 00:23:ae and flags == 0xdc1b, detect select hardware.
On select platforms (Dell OptiPlex 760, Dell OptiPlex 960; perhaps
more), the interrupt appears to go "deaf" after a few seconds. By
matching MAC OUI and flags value, force polling on these select
platforms. I'm not sure if there's any better data available that
shallow in the core. I believe PCI IDs can be fetched with functions
from other libraries and the UUID and DMI data (the most likely to be
useful is SYSPRODUCT) is available in ldlinux.c32.
