Principles when extending structures for generic encapsulation protocol

("concap") support:
|
287 |
|
|
- Stuff which is hardware specific (here i4l-specific) goes in
|
288 |
|
|
the netdev -> local structure (here: isdn_net_local)
|
289 |
|
|
- Stuff which is encapsulation protocol specific goes in the structure
|
290 |
|

which holds the linux device structure (here: isdn_net_device)
