[PATCH] SAA9730: Driver overhaul
o Try to work around some of the undocumented "features" of the SAA9730 o Use netdev_priv() instead of the previous broken mechanism to allocate the private data structure. o Try to make sure we don't leak resources on exit. o No more need to call SET_MODULE_OWNER in 2.6. o Use pci_free_consistent instead of homegrown architecture-specific allocation.
