+ - GET RID OF MACROS
+ - work on all architectures
+ - without CONFIG_X86_64 confusion

+ - no new SIOCDEVPRIVATE ioctl allowed
+ - don't use module_param for configuring interrupt mitigation
+ use ethtool instead
+ - reorder code to elminate use of forward declarations
+ - don't keep private linked list of drivers.
+ - remove all the gratiutous debug infrastructure
+ - use PCI_DEVICE()
