 * The probe, remove, open and close functions, along with the functions they
 * call, are direct copies of the above mentioned driver, modified where
 * necessary to make them work for iPXE.
 *
 * The poll and transmit functions were completely rewritten to make use of
 * the iPXE API. This process was aided by constant referencing of the above
 * mentioned Linux driver. This driver would not have been possible without this
 * prior work.
