[etherlab-users] Installation of the EtherCAT-Master software

[Oliver.Haala at semikron.com]

Hello Andreas,

According to the table of supported hardware it should be possible to run EtherCAT 1.5 Master with kernel 2.6.31. 
Are you sure that its possible? I have had a look at the kernel header file net_device.h. (Version 2.6.31 and .27) 
There are some serious differences between the header files. For example:

$ diff -u net_device.27 net_device.31
...
-       /* Pointers to interface service routines.      */
-       int                     (*open)(struct net_device *dev);
-       int                     (*stop)(struct net_device *dev);
...

The function pointers dont occur in the newer version. That explains the error message, telling me something like that: 
$ make modules
error: 'struct net_device' has no member named 'open'

Is their any quite easy way to deal with that problem or do I have to use a second kernel?

Regards
Oliver
