If we fail to to grab NIC access because the device is not responding (i.e. CSR_GP_CNTRL returns 0xFFFFFFFF), remove the device from the PCI bus, to avoid any further damage, and to let the user space rescan. In order to inform the userspace that a rescan is needed, we send a kobject uevent with "INACCESSIBLE". This functionality is disabled by default, but can be enabled via a new module parameter called "remove_when_gone". In the future we may change this module parameter to include 3 modes instead: do nothing; auto-rescan or; send uevent.
