We discussed this a while ago. Actually fragmentation should be considered the last resort. It if first better to try header compression, to make the frame small enough that it can be sent without fragmentation. I think you had a quick look at using the PPP compression code, but i guess it did not go any further.

We only need to fragment when compression is not possible.

I read about the compression and I still think it is a good idea. Unfortunately, it requires deep packet inspection and would only work for 99% of the IPv4 traffic. Besides, both solutions do not exclude each other.
