Information about napi_struct and net_device

Hello,

I am updating a kernel patch from 2.6.23-rc7 to v3.6, using git
facilities, and I have found that there have been lots of changes in
networking. Now the drivers are all by vendor, and more important,
net_device is not used always, as napi_struct took its place.

I have asked in #kernel but no one answered me, so I subscribed here.
Is there any place I can read about how is it now designed the use of
napi_struct and net_device? I have found a presentation[1] about how
networking was changing etc, and I wondered if there is anything more
precise about how it is actually implemented.

I understand a little why napi_struct, but don't really know much
about the change,

Hope someone can help me,

Javier Domingo
