-To-do items for network drivers
--------------------------------
-
-* Move ethernet crc routine to generic code
-
-* (for 2.5) Integrate Jamal Hadi Salim's netdev Rx polling API change
-
-* Audit all net drivers to make sure magic packet / wake-on-lan /
-  similar features are disabled in the driver by default.
-
-* Audit all net drivers to make sure the module always prints out a
-  version string when loaded as a module, but only prints a version
-  string when built into the kernel if a device is detected.
-
-* Add ETHTOOL_GDRVINFO ioctl support to all ethernet drivers.
-
-* dmfe PCI DMA is totally wrong and only works on x86
-
