Most adapters work properly without them. In the case where ioport resources are not assigned to adapters, this can happen on the large system, drivers' probe function fails like the following, and adapters can not be used as a result. e1000e 0002:22:00.0: device not available because of BAR 2 [0:1f] collisions e1000e: probe of 0002:22:00.0 failed with error -22 These patches corrects behavior in probe function so as not to request ioport resources as long as they are not really needed. These are based on the ioport-free patch of e1000 driver from Auke Kok and Tomohiro Kusumi. * [PATCH 1/3] e1000: make ioport free * [PATCH 2/3] e1000e: make ioport free * [PATCH 3/3] igb: make ioport free Best regards, Taku Izumi
