The last few 2.6 kernel releases have seen a lot of patches removing calls
to a set of network driver support functions, including
, and dev_alloc()
With the integration of networking and sysfs, static net_device
structures have become impossible to use in a safe way; these structures
must now be allocated dynamicly and properly reference counted. See this Driver Porting Series
for details on the currently supported interface.
As of 2.6.3, there are no users of those functions in the mainline kernel
tree. There are, however, certain to be out-of-tree drivers which still
use them. Those drivers will need to be fixed soon; the 2.6.3-mm4 kernel
tree added a patch which removes those functions forevermore. Once that
patch works its way into the mainline kernel, any driver relying upon
init_etherdev() and friends will cease to work until it is fixed.
Don't say you haven't been warned.
